Sub - Miniature Pressure RegulatorItem # 50880-00-20-00

The sub-miniature Series 50 regulator provides regulation of air pressure from 0 to 115 PSI. Available in both relieving and non-relieving versions, the unit's size and shape makes it ideally suited for mounting in dental, medical and laboratory equipment where close regulation and fine adjustments are necessary.

The regulator is supplied with a panel nut for mounting in a 1/2 inch diameter hole. It can be screw driver adjusted, and set with a locking nut, or with the use of a control knob can be continuously adjusted. Ports (2) have 10-32 (M5) threads and are 180° apart on the side of the regulator body. The housing is nickel plated brass.

Several adjustment ranges are available for close regulation in most applications. Special designs are available.
