System compatibility

Compatible with Fisher valve positioners and pneumatic controllers to provide stable regulated instrument air supply.

Function

67CF-1663-38512 is instrument air regulator manufactured by Fisher. It stabilizes instrument air pressure supplied to valve positioner or pneumatic controller. Built-in filter removes particle impurities in instrument air. Overpressure relief function protects downstream pneumatic devices. It is standard accessory for control valve pneumatic loop.

Installation

Follow lockout/tagout safety procedure before installation. Isolate instrument air supply. Mount regulator on pipe or actuator bracket. Connect upstream instrument air line. Adjust output pressure by rotating set knob, test pressure stability and air tightness.

Interface

1/4"NPT inlet/outlet air ports, gauge tapping port, mounting bracket, no LED indicators on 67CF-1663-38512.

Diagnostic

Output pressure drifting: Spring fatigue or diaphragm damage. No air output: Inlet filter blockage or internal valve seat stuck. Air leakage: Diaphragm rupture or seal aging.
