Pneumatic Positioners
Conventional pneumatic positioners receive a pneumatic control signal and translate that into the appropriate pneumatic output signal to the control valve actuator. This positioner technology has been the stalwart for the process control industry for decades, and is still extensively used. We make a variety of Fisher® pneumatic positioners to meet almost any need a customer may have.
 | Fisher 3570 pneumatic valve positioners are used with control valve assemblies to provide an accurate valve stem position that is proportional to the input signal received from a control device. |
 | Fisher 3582 pneumatic, single-acting positioner is used with diaphragm-actuated, sliding-stem control valve assemblies. |
 | Fisher 3610J pneumatic, single-acting positioner is used with rotary actuators to accurately position control valves used in throttling applications. |
 | Fisher 3610JP pneumatic, double-acting positioner is used with rotary actuators to accurately position control valves used in throttling applications. |
 | Fisher 3660 pneumatic, single-acting positioner is used with various actuators on sliding-stem valves for throttling applications. |
 | Fisher 3710 pneumatic positioner is designed for use with either diaphragm or piston rotary actuators. |
