Type 40 Air Pressure Regulator

The Type 40 Air Pressure Regulator is a reliable adjustable air pressure regulator, designed for instrumentation and general purpose use. Test data for the Type 40 shows excellent performance characteristics in such areas as regulated pressure vs. flow, forward-to-reverse flow offset, supply pressure sensitivity, repeatability and stability, among others.

Careful design and selection of quality construction materials throughout ensure long, trouble-free operation, including diecast aluminum housings, finished with scratch- and weather-resistant vinyl paint. A rubberized, soft-seat valve stem provides positive shut-off and “forgives” dirt or other foreign matter. An aspirator maintains downstream pressure and compensates for droop when high flow occurs. The gauge port is convenient for gauge installation and can also be used as an additional full flow outlet. In addition, an integral 60-mesh 304 stainless steel screen blocks foreign particles from entering the output stream.
