Electro-pneumatic valve positioner

Tuesday, 09 June, 2009 | Supplied by: Dwyer Instruments (Aust) Pty Ltd


The Series 275 Precisor III electro-pneumatic positioner is an easy-to-use, high-performance unit that accurately controls the valve stroke of rotary motion valves such as Dwyer Instruments ball or butterfly valves based on an input signal of 4-20 mA from the controller.

Its rugged, durable design makes it suitable for harsh environments. The NEMA 4X (IP 66) enclosure rating protects the microprocessor unit inside the positioner. An output analog feedback signal is included to stabilise any valve system, and easy-to-use functions such as automatic calibration ensure the accuracy of the Series 275.

Low air consumption reduces operating cost, but does not sacrifice the performance of the positioner. The compact design of this unit makes it easy to use with any size actuator. Precisor III positioners feature an LCD screen attached to the outer face of the unit, allowing for an easy inspection of the positioner condition while in the field.
