Pneumatic
Pneumatic actuators use compressed filtered dry or lubricated air as energy power source.
Main features of pneumatic actuators are:
Simple and reliable construction
Compact design
Short operation times
Spring return actuators for fail-safe operation
Suitable for control duty with a 100% duty rate
Most economical way of power actuation for smaller sizes of butterfly valves
Wouter Witzel uses both our own TPN actuator design and products from the world’s best known pneumatic actuator manufacturers.
Pneumatic actuators can be equipped with many ancillaries such as:
Limit switches (direct mounted to actuator or in a switchbox)
Solenoid valve
Throttle valve / throttle block / hydraulic speed control
Positioner
Potentiometer
Electronic position transmitter
Worm gearbox
Air tank
Lever
Air filter regulator
Gauge(s)
