Pneumatic Actuator Valve

Pneumatic Actuator Valve

Pneumatic Piston Actuator benefits from a remarkably simple and practical design. This actuator will open a reverse acting gate valve and is suitable for all types of applications and environments.

To operate the valve, pneumatic pressure is applied on a piston causing a downward movement of the piston, top shaft, down-stem, and the gate. The valve’s gate will remain in the open position until actuator control pressure is released and the actuator spring closes the valve

Main Features

  • Easy to install and repair
  • Lightweight and compact design
  • No special tools is required to repair
  • Easily repaired
  • Designed for long-life services
  • All non-stainless components are coated with Xylan to protect against harsh marine environments
  • Floating piston travels on bearing, eliminating metal-to-metal contact.
  • Designed for safety
  • Valve body penetration is on bonnet above backseat allowing monitoring of backseat and venting well pressure trapped below packing.
  • Heavy-duty compression spring insures stem backseat at low-pressure
  • Bonnet-to-stem, metal-to-metal fire safe backseat protects against bonnet packing distortion or damage in the event of fire
  • Packing retainer has wear bearings that prevent metal to metal contact with bonnet stem
  • Top shaft is free-floating thereby eliminating torque transfer when using manual hold-open device
  • Top shaft indicates position of gate valve.
