The Subminiature Pressure Regulator allows relatively precise pressure regulation in an envelope approximately the size of a miniature pneumatic fitting. The outside dimensions are exactly the same as Beswick's 10-32 threaded needle valves. The inlet port is a 10-32 external thread with an O-ring face seal for leak tight connections. The outlet port orientation is adjustable for easy connections. The device can be supplied in a range of configurations such as tees, elbows, crosses and cartridge mount as well as a wide variety of connection styles such as tube barbs, compression connections or push to connect connections. Inlet pressure rating is 500 psig, and outlet pressure ranges from 5 to 45 psig. It is available with optional elastomeric seal materials to allow excellent fluid compatibility and thermal resistance.
