| The foundation of the PMV positioner system is the P5 pneumatic positioner. Performance of this unit is enhanced with a special high gain, high capacity spool valve assembly providing quick and accurate actuator/valve response. For single and doubleacting applications, the modular design allows for simple addition of an I/P (4-20mA input) converter (such as the EP5) and/or a feedback unit with a variety of feedback options. FNW supplies pneumatic and electropneumatic positioners for both quarter-turn and linear actuators. Contact FNW for optional positioner configurations such as low temp (-40°F/-40°C), reverse acting, feedback units, and characterized cams including split range, equal percent, and square root degree combinations. | | | | Standard Features: |
