Process Safety with Air-Actuated Control Systems

Pneumatic on-off control valves are automation components that convert compressed air energy into mechanical motion to switch fluid flow between fully open and fully closed positions. Their ability to cycle much faster than electric models makes them indispensable for emergency shutdown (ESD) systems and high-cycle production lines. **Spring-return (single-acting)** models ensure process safety by bringing the valve to a fail-safe position (open or closed) in the event of air loss. They offer high sealing classifications (Class VI) for steam, gas, and liquid lines in the chemical, food, and energy sectors.

Actuator Features

  • Single-Acting: Safety shut-off/open via spring power on air loss.
  • Double-Acting: Uses air pressure for both opening and closing cycles.
  • Accessories: Integrated solenoid valves, limit switch boxes, and filter regulators.

Technical Benefits

  • Non-sparking operation suitable for hazardous areas (ATEX).
  • Robust body design resistant to extreme temperatures and high pressure.
  • Long service life with minimal maintenance requirements.
