PNEUMATIC BI-DIRECTIONAL - FLOW REGULATOR SERIES – RBID-FR -1100 (1/4”) / RBID-FR -1110 (3/8”) / RBID-FR -1120 (1/2”)
DESCRIPTION
The Rtork is a comprehensive line of high-flow pneumatic spool valves designed for Pneumatic 3 Way 2 Position, Pilot Operated, Normally Universal, Spring Return, These valves are positively sealed for low-pressure applications up to 145 psi / 10 bar. They are primarily designed to handle the high flow demands of large swept volume and / or fast-acting valve actuators controlling pipeline ESD, process plant, or similar applications. When configuring valves, you have the option to choose between 3/2 and 5/2 positions. Additionally, valves can be set as Normally Closed, Normally Open, or Normally Universal. It's important to keep in mind that the pilot operating pressures are higher for Normally Open configured valves.
FEATURES
Bi-directional Flow regulator controls the flow separately in each directions Typical application is the speed control of an actuator
Suitable for the applications include marine environment, oil and gas productions, chemicals and food processing, medical analysis, corrosive atmosphere etc.
