Frequently Asked Questions

A pneumatic actuator is a device that converts compressed air energy into mechanical motion (usually rotary or linear) to operate a valve or mechanical device.

When compressed air is supplied to the actuator chamber, it creates pressure on a piston or diaphragm. This pressure is converted into motion — linear (for cylinders) or rotary (for rack and pinion or scotch yoke actuators) — to operate the valve.

  • Single Acting (Spring Return): Uses air pressure to move in one direction and springs to return to the fail-safe position.
  • Double Acting: Uses air pressure for both opening and closing directions; no internal springs.

  • Fast and reliable operation
  • Simple design and easy maintenance
  • Safe for hazardous environments (no spark risk)
  • High force/torque output
  • Long service life

  • Rotary Actuators: Provide 90° or 180° turning motion (for ball, butterfly, plug valves).
  • Linear Actuators: Provide straight-line motion (for gate, globe, diaphragm valves).

Actuator size is chosen based on valve torque requirements, air pressure, and a safety factor (typically 20–30%). The actuator must provide adequate torque even at minimum air pressure.

  • Solenoid Valve
  • Air Filter Regulator (FRL)
  • Limit Switch Box
  • Positioner (for modulating control)
  • Speed Controller
  • Manual Override or Gearbox

Inspect every 6–12 months, depending on the operating cycle, air quality, and environmental conditions. Replace seals or springs as required.

  • Fail-Open (FO): Valve opens when air supply fails.
  • Fail-Close (FC): Valve closes when air supply fails.
    This configuration is determined by spring arrangement or air port connection.
