PNEUMATIC 3-2 WAY AIR OPERATED SPOOL VALVE SERIES - RAOSV -600 (1/2”) / RAOSV -610 (3/4”) / RAOSV -620 (1”) / RAOSV -630 (1.1/2”) / RAOSV -640 (2”) and 5-2 WAY AIR OPERATED SPOOL VALVE SERIES - RAOSV -700 (1”)
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
- High-flow efficiency: 1" NPT stainless steel port blocks with a Cv value of 14.2, enabling rapid actuator response and supporting high-volume flow demands.
- Corrosion resistance: Constructed from 316L stainless steel, compliant with NACE for sour gas media, suitable for offshore and corrosive atmospheres.
- Spring return operation: secondary operator configuration ensures automatic reset to the safe state when pilot pressure is removed, enhancing operational safety.
- Versatile installation: Optional port block orientations (direct/side entry) eliminate costly reducer fittings, adapting to diverse tubing sizes and system layouts.
- SIL 3 capability: Meets IEC 61508 design requirements for Safety Integrity Level 3, ensuring reliability in safety-instrumented functions for high-risk operations.
- Arctic-ready performance: Equipped with fluorosilicone (AL) seals, operating at -60°C to +100°C, ideal for extreme low-temperature environments like arctic oil/gas fields.
