Fisherr 3710 and 3720 Positioners and 3722
Electro-Pneumatic Converter
Fisher 3710 pneumatic and 3720 electro-pneumatic
positioners are designed for use with either diaphragm
or piston rotary actuators. These positioners provide a
valve ball or disk position for a specific input signal.
The 3710 provides a valve position in response to a
pneumatic input signal. The 3720 is created by the
addition of a Fisher 3722 electro-pneumatic converter
to the 3710 positioner. The positioner provides a valve
position in response to a DC current input signal. Either
type can easily be configured as single- or doubleacting for rotary actuators.
