       The Electro-Pneumatic Valve Positioner stroke accurately by DV 4~20mA current signal being input from
controller. It changes the current signal into air pressure to control 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.
       VS-1000R(rotary) and VS-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.
