Electro-pneumatic Positioners Series 703/704fc

The Electro-Pneumatic Positioners Series 703/704FC are used as final controlling element for operation of pneumatic Rotary/Linear valve actuators in correspondence with an input signal of 4-20 mA DC or split ranges.

The Positioners are based on a force balance design for control application that requires a high degree of reliability and repeatability at an economical cost.

The Positioners can handle the supply pressure up to 100 psig for higher pressure industrial pneumatic and process control system requirements.
