Emerson FISHER 67DFR – 25/C4: Pressure Reducing and Filter Regulator

The FISHER 67DFR – 25 regulator is a high – performance pressure – reducing filter regulator in the FISHER 67D series. Here is its introduction:
Model Characteristics: It is a direct – acting regulator with an aluminum body, equipped with a filter and an internal relief valve. It has the Smart Bleed™ function. That is, when the supply pressure is lost, the internal check valve can relieve the pressure from the outlet.
Design Advantages: It features a compact design and is light – weight, which facilitates installation and portability. The optional stainless – steel material construction enhances its corrosion resistance and service life. The internal relief function improves the safety performance, and the filter can effectively prevent impurities from entering the valve, protecting the valve and downstream equipment.
Pressure Parameters: The maximum inlet pressure is 250 psig (17.2 bar), and the outlet pressure range has multiple options, such as 0 – 125 psi. The maximum emergency outlet pressure is 150 psi (10.3 bar) above the outlet pressure setting, but not exceeding 250 psi (17.2 bar).
