Sierra Introduces New Line of Gas Flow Control Valves

Published: June 26, 2015 |  Author: Lars Kristian Salvesen

SmartVO™ control valves offer a robust and field-proven direct-acting electromagnetic proportional control valve technology to perform over a wide variety of temperature and pressure variations in the gas stream.

You can even locally adjust response characteristics for multiple applications or system pressure design changes.

When integrated with a flow sensor or pressure transducer and a proportional electronic controller, SmartVO control valves are capable of providing steady and precise control of gas flow rates or pressures.

“We are very excited about our new line of valves,” says Matthew Olin, CEO. “We have manufactured control valves for over 30 years as part of our mass flow controller product line—so they are field proven. The difference is, now we have repackaged an elegant and high quality valve-only product line. In the case of our SmartVO, the customer already has flow or pressure metering in place and just needs precision control.”

Sierra’s SmartVO line of valves consists of fast-response control valves which provide immediate response to control signal changes and operate over a wide pressure differential range. All models are electromagnetic proportional control valves designed for use in closed loop flow or pressure control systems. They are ideal for on/off or partial flow control of air and process gases in ranges from 0 up to 1000 slpm.
