YT1000L Type Electric-Pneumatic Valve Positioner

YT1000L Type Electric-Pneumatic Valve Positioner is a device that receives direct current signal from controller or control system and transport air to straight trip pneumatic actuator to control valve opening .

Positioner Technology feature

  • Within 5~200Hz no resonance phenomenon
  • Direat action and reaction, single action and double action canbe easily exchange
  • As resonance caused by small type actuator, it can be resolved by adding positioner throttles.
  • Air comsumption less, the economy is good
  • Can be split range control within 1/2 without exchanging parts.
