High Pressure Coaxial Valves for High Cycle Life Applications

Coaxial Valve Cycle Life Extended By as Much as Ten Times Conventional Valves

VAX High Pressure Coaxial Valve

Assured Automation announces a new line of RSG High Pressure Coaxial Valves for applications that require fast actuation, and strict durability and reliability. These compact automated valves combine a process valve and actuator in a single integrated unit with only one moving part. The VAX valve has a coaxial design offering high flow rates with minimal pressure loss, while extending the RSG’s cycle life by as much as ten times that of conventional valves. The electric version of the RSG functions like a direct acting solenoid valve.

Durability is a key advantage to the RSG valve. These valves do not leak, coils do not burn out.

Shut-off speed is fast, occurring in as little as 0.25 milliseconds in either direction.

A pressure balanced design with spring return allows the RSG valve to function regardless of system pressure or pressure differential on either side of the valve. The valves are available in 2-way or 3-way configurations with pressure ratings up to 600 PSI.

Since the valve works with the forces of flow instead of against them, it is suitable for most vacuum, gaseous, gelatinous, highly viscous, pasty, aggressive or contaminated, or recycled fluids and gases from vacuum to 600 PSI.

RSG Coaxial Valves Configurability

Their ability to be customized makes the RSG valve a preferred solution in difficult applications. Thua valve is available in electric and pneumatic versions. Direct-acting or air-actuated versions as well as two-way valves are available in brass or SS; 3-way valves are available in brass. The valves come Normally Open or Normally Closed.

RSG Coaxial Valves Featured Applications

The RSG valve is particularly well suited for high cycle applications. For example, a dying plant in Shoemakersville, PA uses a 140-foot long fabric dryer in their fabric dying process. The conventional solenoid valves used to control the natural gas jets in the dryer’s built-in burner was failing too often. Their internal diaphragms became brittle and frequently broke, slowing down the fabric dying process.

“To keep competitive, we needed to improve the throughput in our drying process,” recalls Rick Weller, plant engineer at Wolf Dye and Bleach Works, Inc. “In our frustration, we asked the engineers at Assured Automation to recommend better solenoid valves. When they identified the source of our problem, they recommended we switch to the Assured Automation RSG valve.”

The RSG valve’s wear-compensating seat proved to be the right solution, with its lower probability of catching fire and is lower susceptibility to decay under increased oxygen conditions. The 110-foot fabric dryer equipped with 12 burners and 36 valves, drying fabric at the rate of 25-75 yards per minute, has been in continuous service since the RSG valves were installed over two years ago, with no maintenance.

“We pride ourselves as a progressive company that takes our responsibility to protect the environment seriously,” explains Weller. The Assured Automation RSG valve enables us to maintain a competitive advantage, and while better controlling the flow of natural gas, improving safety, and minimizing any environmental impact.”
