FISHER 67d Series FISHER 67DFSRPressure Reducing Regulators: Stainless Steel Body with Filter and Internal Relief

The filter – pressure reducing valve is a device that integrates the functions of filtration and pressure reduction. FISHER brand filter – pressure reducing valves, such as the 67C and 67D series mentioned before, are widely used in the industrial field.
Working principle: Gas or liquid first passes through the filtration component, where impurities, particles, etc. are intercepted and filtered out to ensure that the medium entering the pressure – reducing part is clean. Then the medium enters the pressure – reducing component, and the input higher pressure is adjusted to a set stable output pressure by adjusting components such as the spring and diaphragm.
