       The Electro-Pneumatic Valve Positioner stroke accurately by DV 4~20mA current signal being input from

controller. It change the current signal into air pressure to contorl the pneumatic actuator, so as to control the

opening of the valve 

      This product is convenient to change between direct action and back action, or change between spring

return and double acting.

       It has the features of low air consumption, easy to operate the Zero Adjust and Span Adjust, quick acting

and simple to connect the Feedback Lever.

       HT-1000R(rogary) and HT-1000L(linear) all can select and install the DC 4~20 mA Feedback Unit.

  • There is no vibration in the range of 5-200 HZ.
  • Can set 1/2 Split Range with simply operate, do not need to change part.
  • Zero & Span adjustment process is simply.
  • Convenient to change between direct action and back action, or change between spring return and double acting.
  • Feedback lever connection is easy.
  • Acting fast and accurately.
  • It is economical due to less air-consumption.
  • Small pneumatic actuator can use the orifice of Pilot valve to avoid vibration.
