Electro-Pneumatic Positioner

Electro-Pneumatic Positioner accurately controls valve stroke in response to an input signal of 4-20mA from controller.

Main Features and Functions:

• It is compatible with most controllers.
• Response time is very fast and accurate.
• Split range 4-12mA or 12-20mA can be set by simple operating. (inform us when ordering as the parts are different)
• Low air consumption.
• Simple Direct/Reverse Action change.
• Simple Zero & Span adjustment.
• Position transmitter or limit switch is available as internal or external option on the positioner. However, positioner is non-explosion type when internal option has been selected. In case of external option, both the positioner and the external products can be selected with explosion-proof certified products. Orifices can be installed even in the field to minimize the hunting occurence and optimize operating conditions.
• A/M switch can be used to direct supply ait to the actuator or to manually operate the positioner or valve without any signal.
• It has IP66, Type 4X (FM) ingress protection grade.
• Epoxy polyester powder coating resist the corrosion process.
• Maintenance of the positioner is easy because of modularized inner structure.
