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.

Solution:

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.

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

Application:  

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

Coaxial Valves vs. Ball Valves for On/Off Applications

For basic on/off service in process, water, or virtually any application, a ball valve is a common choice. There is, however, another option that should be considered. Coaxial valves are an excellent choice for on/off applications also, and have MAJOR advantages. Read below to learn why a VA Series coaxial valve might be the best choice for your application.

VA Series Coaxial Valve Advantages

  • Smaller
  • Lighter
  • Faster
  • Less Expensive
  • Higher Cycle-life
  • Safer (no moving parts)

Coaxial Valves vs. Ball Valves for On/Off

This is an actual size comparison of 1″ NPT ON/Off valves with dual (open & closed) proximity sensor limit switches.

Details of these Advantages

Smaller

The VA series coaxial valve with integral actuator is only slightly larger than JUST THE VALVE in the ball valve assembly. The limit switches are tiny, and attach to a simple bar that clamps on to the valve body using simple set screws. If a solenoid valve is to be used (not shown above) it is a NAMUR mounting interface to maintain the compact streamlined assembly.

Lighter

While the VA valve may be slightly larger than the ball valve equivalent. The fact that it includes the actuator eliminates the additional weight of the rotary actuator needed on a ball valve assembly. This makes it much lighter than an air actuated ball valve of equal size.

Faster

The volume of air required to actuate the VA series is much less than that needed vs. a ball valve of the same size. The shuttle inside the valve has a relatively short travel distance.

Less Expensive

The VA series air-operated coaxial valve costs far less than an air-operated ball valve. The savings can be as much as 50% or more. You don’t have the added expense of an actuator, or that of the time and hardware needed to install it.

The cost of operation is also less due to the lower volume of air consumed.

Higher Cycle-Life

The higher cycle-life also provides more value. It extends the life of the valve and requires less frequent seal replacement. VA valves have reached 5 million cycles! This saves on replacement seals, maintenance costs, and reduces system down time.

Safer

There are no external moving parts on the VA coaxial valves. Certain limit switches do move externally on the rotary actuators used in ball valve assemblies.

VA Coaxial Valve vs. Ball Valve Comparison (1″ NPT valves)

VA Coaxial Valve 3-piece Ball Valve w/
pneumatic actuator
Dimensions 5.6″ x 3″ x 2.7″ 7.55″ x 3.76″ x 8.5″
Weight 4.15 lbs. 8 lbs.
Cycle Speed .02 (air stroke)
.04 (spring stroke)
.05 (spring stroke)
.06 (air stroke)
Cv 17 116
Cost (no limit switch) $175 (DA)
$184 (SR)
$376 (DA)
$473 (SR)
Cost (dual prox. limit switch) $355 (DA)
$364 (SR)
$586 (DA)
$683 (SR)

Disadvantages

Lower Cv

As you can see in the chart above, there is one disadvantage when using VA series valves. The Cv is much lower. This makes a full-port ball valve a better choice for applications with high flow rates, or where minimal pressure drop is a critical factor.

Fluid Compatibility

The VA series has a limited selection of seal materials which includes Buna, EPDM, and Viton®. This limits the media that can be controlled to those that are compatible with any of the 3 choices.

When You Need a Diverter Valve for Ink, Paint Dispensing, and Caustic Media

Diverter valves are one type of 3-way valves. Unlike modulating and mixing 3-way valves that combine two inputs into one output, diverter valves separate one input into two outputs. Diverter valves are frequently used in control processes because they are less expensive and require less space than using multiple 2-way valves to divert flow. Although multiple 2-way valves can achieve the same goal of diverting, or mixing, the additional cost of purchase, installation, and maintenance on two 2-way valves, and the larger footprint required, more than justifies the use of a single 3-way valve. Factoring in the cost of actuation, a single actuated 3-way valve can save thousands of dollars over multiple 2-way valve configurations.

Compact Valve for Aerospace Test Application

VA Series Compact On/Off Valve for Aircraft Engine Test Stand 

Problem:

A major aircraft component testing company required a compact valve for a customized panel designed to meter airflow in an aircraft engine sub-component test application.

The ball valves currently being used had many limitations. The ball valve actuators were large, requiring a deeper, more expensive panel. Installation and removal of the ball valve required disassembling the two items in this tight location. The cycle life of the ball valve was limited requiring frequent replacement or repair of seals.

Solution:

Test engineers called Assured Automation as they had successfully used their automated valves and flow meters for previous jobs.

Compact ValveAssured Automation’s product specialist suggested they use the VA Series compact, pneumatically controlled on/off valve.

The VA Series combines a pneumatic actuator and fast on-off control valve into one body, eliminating packing glands, actuators and mounting kits, saving space as well as money.

Since the actuator is part of the valve, the VA Series costs are greatly reduced when compared to standard actuated valves. Operating life has been tested to well over 1,000,000 cycles due to the balanced design which reduces friction and wear.

Result:

The VA Series compact valve was installed into the custom modular test panel with remarkable success. The VA valves were compact, saving space in the panel and had a long operating life which is a huge costs savings.

According to the test engineer:

This panel can be field-swapped in 10 minutes and allows for a range of valve size options for various flow ranges while keeping interface hardware the same.  Prior design (non-Assured Automation) had remotely located valves that were far more difficult to swap and required custom modification of the enclosure, could not be hung on-panel as these are, and were prone to failure around the mount making leak detection virtually impossible.   ~ R. Boise

Compact Valve VA Series

Customized panel with Assured Automation compact valves for metering airflow in aircraft engine sub- component test application

VA Series Product Description

The VA Series (Valve + Actuator) compact valve comes in 3/8” to 2”.  Body is nickel plated brass with Viton® (standard) or BUNA-N or EPDM (optional) seals. Ideal for high cycle and high Cv applications including:
