Product description
Control signal: Receive 4-20mA electrical signal or switching signal, and the pneumatic positioner converts the signal into a pressure change (usually 0.2-1.0mpa).
Driving process: compressed air drives the piston movement, drives the valve stem to rotate, and the valve plate is from 0° (fully closed) to 90° (fully open), adjusting the Angle to achieve flow control.
Type:
Switch type: two-position control (full open/full closed), suitable for simple open and close scenes.
Adjustable type: equipped with positioner, can accurately control the opening, for continuous adjustment system.
Core advantage
Fast response: Pneumatic drive action time is short (usually only a few seconds), suitable for high frequency operation.
High reliability: simple structure, low failure rate, suitable for explosion-proof environment (no spark risk).
Easy maintenance: Modular design, easy to disassemble and replace seals or valve plates.
Energy saving and environmental protection
