The GO Regulator PR-57 Series is a high-flow pressure reducing regulator designed for precise downstream pressure control in demanding gas and liquid process applications. The regulator provides stable outlet pressure regulation with excellent sensitivity, rapid response, and reliable repeatability under varying inlet pressures and elevated flow conditions. Its heavy-duty diaphragm-operated design delivers smooth throttling performance and dependable long-term operation in continuous industrial service environments.

The PR-57 Series is engineered for applications requiring robust construction, corrosion resistance, and stable pressure control at high flow capacities. Standard construction materials include 316 stainless steel, brass, Monel, and Hastelloy configurations for compatibility with corrosive, toxic, oxidizing, and high-purity media. Multiple seat and elastomer material options are available to optimize chemical compatibility, shutoff performance, and operational durability across a broad range of operating conditions.

Available configurations include multiple outlet pressure ranges, high Cv flow capacities, threaded and flanged process connections, pressure gauge ports, panel mounting arrangements, and specialty clean-service options for analytical and semiconductor applications. The regulator is suitable for both gas and liquid service while maintaining reliable pressure stability at elevated operating pressures and flow rates.

Typical applications include gas distribution systems, compressor systems, semiconductor support equipment, chemical processing equipment, analytical instrumentation, pilot plants, hydraulic systems, process skids, laboratory installations, and industrial process systems requiring stable high-flow pressure reduction and dependable process control.
