Supplier Fisher Type 67CFR-239 Instrument Air Pressure Regulator
WWW.DISTRIBUTORALATINDUSTRI.COM | Supplier Fisher Type 67CFR-239 Instrument Air Pressure Regulator | Fisher Type 67CFR-239 Instrument Air Pressure Regulator is a compact, direct-operated pressure reducing regulator designed to supply clean, stable, and accurately regulated air pressure for pneumatic instrumentation and process control equipment. It is widely used to provide regulated instrument air to valve positioners, pneumatic actuators, I/P converters, controllers, and other pneumatic devices in industrial automation systems.
Supplier Fisher Type 67CFR-239 Instrument Air Pressure Regulator
The regulator automatically reduces high inlet pressure to a constant downstream pressure, ensuring reliable performance and protecting sensitive pneumatic equipment from pressure fluctuations.

Operating Principle
The Fisher 67CFR-239 uses a diaphragm and spring-loaded mechanism to regulate outlet pressure. High-pressure instrument air enters the regulator through the inlet port and is reduced to the desired downstream pressure by adjusting the spring compression using the external adjustment screw. As downstream pressure changes, the diaphragm automatically modulates the valve opening to maintain a stable outlet pressure.
