Emerson Fisher Gas Pressure Regulator Internal 67CFR-239 250 PSI

Fisher 67CFR-239 direct-operated regulators and filter regulators are typically used to provide constantly controlled, reduced pressures to pneumatic and electropneumatic controllers and other instruments. These are suitable for most air or gas applications. Other applications include providing reduced pressures to air chucks, air jets, and spray guns.

 

Principle of Operation

Downstream pressure is registered internally on the lower side of the diaphragm. When the downstream

pressure is at or above the set pressure, the valve plug is held against the orifi ce and there is no fl ow through the regulator. When demand increases, downstream pressure drops slightly allowing the spring to extend,

 

moving the stem down and the valve plug away from the orifice. This allows fl ow through the regulator.
