Emergency Shutdown Valves In Stock

The Problem:

A large chemical company was looking to purchase a rush project for emergency shutdown valves for their gas and chemical lines to meet insurance requirements. The automated ESD valves needed to be tied into their main fire alarm system to fail closed upon a triggering of their fire alarms. The specification called for full port API607 firesafe 150# flanged ball valves with spring return rack & pinion pneumatic actuators, FM Approved explosion proof solenoids and explosion proof limit switches.

The Solution:

After obtaining quotes from several major valve brands with delivery dates over 10 weeks the customer reached out to Assured Automation. Using the Assured Automation online valve configurator the customer was able to get a price, datasheet and 3D CAD file on each assembly within minutes.

After confirming a firm delivery date with the sales team, the customer was able to place an official order the same day. Assured Automation was able to assemble, test and ship the entire project in two days.

Fugitive Emissions & Valve Regulations

What are Fugitive Emissions?

Fugitive emissions or FEs refer to the unintended release of environmentally harmful gases or vapors from industrial activities or facilities. It is estimated that 51% of these fugitive emissions have been attributed to valves.

In a typical facility most emissions are from valves and connectors, the most prevalent components, which often number in the thousands. Seal or gasket failure due to normal wear or improper maintenance is the major cause of these valve emissions.

Besides contributing to the loss of salable product, fugitive emissions pose a risk to the health and safety of workers as well as to the surrounding communities.

A Short Overview of Fugitive Emission Regulations

In October 1948, the mill town of Donora, Pennsylvania was covered by a toxic smog unintentionally released by the local steel manufacturing facilities.

After 5 days, the toxic gases resulted in the sickening of thousands and death of 20 in the community. Now considered one of the worst air pollution disasters in the nation’s history, the “Donora Incident” demonstrated the need for air pollution control and lead to the creation of the first clean air programs in the US.

In response to worsening industrial pollution the Environmental Protection agency (EPA) introduced the US Clean Air Act, the first federal legislation regarding air pollution control. Since that time increasingly stricter air pollution policies have been implemented at the US Federal and State levels.

Germany also began instituting air pollution control regulations in 1964 titled “Technical Instructions on Air Quality Control” (Technische Anleitung zur Reinhaltung der Luft) commonly referred to as the TA Luft.

During the late 1980s, EPA legislation was amended to include petroleum refineries and chemical processing plants that emit volatile organic compounds (VOC’s) and hazardous air pollutants (HAPs). The agency began conducting audits in hopes that companies would willingly implement emissions reductions.

In order to reduce the emission of fugitive VOCs and HAPs, the EPA instituted Leak Detection and Repair (LDAR) regulations, a system of procedures a facility utilizes to locate and repair leaking components which includes EPA Method 21, a method for determining VOC leaks from process equipment in parts per million. EPA Method 21 pertains to valves, flanges and other connections, pumps and compressors, pressure relief devices, process drains, open-ended valves, pump and compressor seal system degassing vents, accumulator vessel vents, agitator seals, and access door seals.

By the late 1990’s, the EPA determined that many facilities were under-reporting emissions, failing to implement Method 21 sufficiently to meet emission reduction targets.

It was estimated that 40,000 tons of VOCs were being emitted annually from valves of petroleum refineries alone. By the early 2000’s many refineries agreed to implement official LDAR Programs to avoid litigation. 

Fugitive Emissions Valve Standards

When facilities do not meet the EPA’s Clean air requirements, consent decrees are negotiated with the manufacturing facility, typically resulting in the implementation of a formal Leak Detection and Repair (LDAR) program which implements Method 21 valve VOC monitoring.

Currently, It is believed that 80% of fugitive emissions from valves are emitted through the valve stem of linear valves (gates and globes) due to the rising/rotating of the stem through the packing system and the difficulty of proper sealing.

As the EPA continues to refine its standards for the LDAR process there is a push that new valves used in refineries to be certified as “Low E Technology”. The EPA defines a Low E Valve as:

A valve (including its specific packing assembly) or valve packing for which the manufacturer has issued a written warranty that it will not emit fugitives at greater than 100 ppm, and that, if it does so emit at any time in the first five years, the manufacturer will replace the valve

The push for “low Emissions Valves” and “low Emissions Packing” has prompted many standards organizations such as API, ANSI, ISO, MESC, ANSI and TA-Luft to establish valve and packing test standards which assess fugitive emission performance. 

Examples of Fugitive Emissions valve standards:

American Petroleum Institute Standards (API) currently has three valve/packing emissions standards tests.

  • API 622 Type Testing of Process Valve Packing for Fugitive Emissions. This is a test of the valve packing alone.
  • API 624 Type Testing of Rising Stem Valves Equipped with Graphite Packing for Fugitive Emissions. This test evaluates the total performance of the valve, not just the valve packing, The Packing used in an API 624 test must have passed API 622 Requirements.
  • API 641 Type Testing of Quarter-turn Valve for Fugitive Emissions. This is the type test for quarter turn valve designs evaluating low emissions performance over an accelerated life cycle

International Organization for Standardization

According to ISO testing guidelines the test media must be methane and the test method must be EPA’s Method 21. The EPA has determined that methane is the most destructive to the environment.

  • ISO 15848-1:2015 (Type Testing) specifies testing procedures for evaluation of external leakage of valve stem seals (or shaft) and body joints of isolating valves and control valves intended for application in volatile air pollutants and hazardous fluids.
  • ISO 15848-2:2015 (Production Test) specifies test procedures for the evaluation of external leakage of valve stems or shafts and body joints of isolating valves and control valves intended for application with volatile air pollutants and hazardous fluids.

TA Luft -German Technical Guidelines for Air Pollution

  • Guideline VDI 2440 refers to average gas-like emissions for differing gasket systems.

A much less stringent standard compared to ISO 15848, TA Luft only deals with the sealing system of the stem passage with very general testing requirements.

Magnetic Flow Meter Basics

Magnetic Inductive Flow Meters

A magnetic flow meter, also referred to as mag flow meter or magmeter, is a volumetric flow meter that measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm.  Magnetic flow meters will typically not work with hydrocarbons, distilled water, non-aqueous solutions and non-conductive solutions.

Magnetic flow meters utilize Faraday’s Law of Electromagnetic Induction to determine the velocity of a liquid flowing in a pipe.  Magnetic flow meters consist of a nonmagnetic flow tube, liner, electrodes and electromagnets to generate a magnetic field. In magnetic flow meters, a magnetic field is generated and channeled into the liquid flowing through the pipe.

Operating according to Faraday’s Law, signal voltage (E) is dependent on the average liquid velocity (V) the magnetic field strength (B) and the length of the conductor (D) which in this instance is the distance between the electrodes.

Faraday’s Formula
E is proportional to V x B x D where: 

E = The voltage generated in a conductor
V = The velocity of the conductor
B = The magnetic field strength
D = The length of the conductor

Mag Meter Operation

The liquid flowing through the pipe is the conductor, and electromagnetic coils surrounding the flow tube generate the magnetic field. The signal is sensed by the two electrodes embedded on opposite sides of the flow tube. The flow signal at the electrodes is directly proportional to the flow velocity, the intensity of the magnetic field, and distance between electrodes.

Magnetic flow meters do not require much upstream and downstream straight runs so they can be installed in relatively short meter runs. 

Advantages of using Electromagnetic Flow Meters

The main advantages of using magmeters is that they feature an obstruction-free design with no moving parts which eliminates flow impediment, requires less maintenance and can be used on very large line sizes.  Accuracy over a wide flow range can be as good as ±0.5%

Mag Meter obstruction free flow path and no moving parts

Mag meters perform extremely well in many municipal and processing applications and is the meter of choice for measuring conductive liquids such as water or slurry. Magmeters also have the advantage of being able to measure both very low flows and very high volume flow rates.

Disadvantages of using Magnetic Flow Meters

Magnetic flowmeters are only effective on conductive fluids, and materials such as unmixed hydrocarbons and gases cannot be measured. However, magnetic materials themselves may also present problems, as hydrodynamic effects can alter the normal flow pattern and disturb the velocity rate enough to interfere with operations. Depending on their size and capacity, magnetic flowmeters can be relatively heavy, and those with higher corrosion and abrasion resistance can be expensive.

Typical Industries Where Magnetic Flow Meters are Used

  • Water/Wastewater Industry
  • Brewing, Distilling, and Wine Making
  • Chemical
  • Food and Beverage
  • Power Generation
  • Pulp and Paper
  • Metals and Mining
  • Pharmaceutical
  • HVAC
  • Mining/Mineral Processing

Magnetic Flow Meter Selection

Key questions which need to be considered before selecting a magnetic flow meter

  • Is the fluid conductive or water based?
  • Is the fluid or slurry abrasive?
  • Minimum and maximum flow rate for the flow meter?
  • Minimum and maximum process pressure?
  • Minimum and maximum process temperature?
  • Is the fluid chemically compatible with the flow meter wetted parts?
  • What is the size of the pipe?
  • Is the pipe always full?
  • Do you require an integral display or remote display?
  • Do you require an analog output?

Magnetic flow meters require a minimum medium conductivity for the technology to measure flow. This chart provides a general guideline on conductivity of common media.

Fire-Safe Shut Off Valves for Distillery Application

Problem: A local distillery was directed by their insurance agency to incorporate fire safe shut off valves on their storage tanks to ensure closure of outlet valves to isolate flammable liquids in the event of fire.


Fire Safe Shut off Valves

The head brewer at the distillery contacted us as they had successfully used Assured Automation automated valves and flow meters for previous jobs.

An Assured Automation product specialist suggested the use of the FM Fire-Safe Series. These FM approved thermal shut off valves are spring loaded with a thermal link. When the link burns in fire conditions the spring brings the API607 firesafe ball valve to a closed position, preventing the release of flammable liquids which could potentially feed a fire.

FM Fire Safe Series

Having a fire safety shutoff system in place is very important at any facility which deals with flammable liquids or gasses. The Assured Automation FM Fire-Safe Thermal and Electro-Thermal Emergency Shutdown Valve assemblies are constructed to automatically close or open and mitigate any conditions which could be deemed potentially dangerous.

Both the ball valve and butterfly valve designs are Factory Mutual (FM) approved. Thermal valves have thermal links which operate the valve at a predetermined temperature. The electro-thermal valve adds an electro-thermal link which can be triggered by a low power electrical current impulse, such as a smoke detector alarm. Both valve designs can also be operated manually without affecting the viability of the link.

The FM Fire-Safe valves are the perfect choice when the flow of hazardous liquid or gas needs to be completely halted due to the presence of fire. The valves can also be implemented in fire suppression systems, to release fire retardant in an isolated area instead of the entire plant.

3-piece Ball valve designs are available in sizes from 1/2 to 6”; thermal activation temperatures from 165 to 360° F; threaded, socket weld, butt weld, and flanged connection configurations. Butterfly valves are available in sizes from 2” to 12”; thermal activation temperatures from 165 to 360° F; carbon steel or 316 stainless steel.

2 Ball Valves Mounted on One Actuator

Project Showcase: Specialized equipment manufacturer requires 2 brass ball valves mounted on one pneumatic actuator for infrared boiler thermometer application

2 Ball Valves One Actuator

Specialized equipment manufacturer requires 2 ball valves on one actuator

Customer Type Specialized Equipment Manufacturer
Application Infrared Boiler Thermometer
Valve Series 101 Series Nickel Plated Brass 2 -Way Ball Valve
Actuator Series O Series Double Acting Pneumatic Actuator
Valve Size  3/8″, 1 1/2″
# of Valves 50
Sales Person Mike O
Valve Assembly Technician Mike T


A manufacturer of specialized performance and maintenance equipment required a 1½“ and a 3/8” ball valve be mounted on a double acting pneumatic actuator as part of an infrared thermometer assembly for in-situ mounting on furnaces for sensing internal gas temperatures.


Assured Automation product specialist, Mike O’Neill, supplied 101 Series 2 way brass ball valves and O Series spring return pneumatic actuators.


101 Series Ball Valves

The 101 Series is a full port, brass, NPT threaded end actuated ball valve. It can be equipped with a manual handle or with direct mount pneumatic or electric actuators. The direct mount actuators eliminate the valve-actuator mounting kit, which adds unnecessary height and expense. Available in ¼” to 3”



O Series spring return pneumatic actuators offer a simple and cost-effective solution for your valve automation needs.  For use on quarter turn (90 degree) ball valves, plug valves, dampers, and resilient seated butterfly valves.

Spring return pneumatic actuators use compressed air to move the piston in one direction, and a spring to push it back in the other when the air is stopped and allowed to vent.

The most important aspect of a spring return actuator is that it offers a “fail-safe” position which means that if the air supply is lost, or electric power to the solenoid that controls the air is lost, the valve will travel to this position using the force of the spring(s). This could be either open or closed, whichever offers a safer outcome.

These dual scotch yoke style actuators have higher torque values at the start and end of the stroke.

Long time team member, Mike Thompson was the assembly lead on this project which consisted of over 25 automated valve assemblies.

Globe vs. V Port Ball Valves for Flow Control Applications

In most process applications there are two different types of valves used: on/off and control. On/off valves allow full flow or stopping flow completely. Control valves, in contrast have the ability to control the AMOUNT of flow, also known as throttling.

V-Port Ball Valves

V-Ball Control Valve

V Series V-Port Ball Valve

V-Port ball valves are a specialized ball valve that offer:

  • Suitability for coarse control applications
  • Reliable shutoff
  • Many different V-Port balls options available to accommodate different flow ranges with the same valve body, most common being 60˚, 30˚, and 15˚

Globe Valves 

GVI Series Globe Valve

Globe valves use linear actuation and offer:

  • More precise control due to a more linear flow curve (See Figure 3 below)
  • Do not suffer uneven wear in the mid positions
  • Typically have higher pressure drops than V-Port valves

However, they do not typically provide a bubble tight shutoff. They also require greater force or a larger actuator to seat the valve.


V Port Ball Valve and Globe Valve Comparison


V Port Valve Globe Valve
Function 2-way flow control 2-way flow control,
3-way mixing,
3-way diverting
Positive Shutoff YES Not leak free
Control Capability Coarse Fine
High Duty Cycle NO YES (constant)
Flow Capacity Higher Lower
Cavitation Prevention
High Temperature Preferred
Ease of Maintenance Preferred
Cost More economical
