The POSR-1 is a low-cost, pilot-operated pressure reducing steam regulator with bellows seal design that eliminates sticking. Pilot and main valve trim are hardened 416 SST for long life. These regulators can maintain outlet pressure within +/- 5% and are commonly used in large steam heating installations and process application with coolers, pasteurizers, sterilizers, vulcanizers, and other equipment. Available without the pilot as a pressure-loaded regulator.
Cashco manufactures a proprietary line of self-contained regulators and control valves. The regulators are self-sufficient valves that control the flow based on line pressure at the regulator. By contrast, control valves control flow based on an external signal coming from a controller. Cashco valves control liquids and gases in industrial applications.
