The GO Regulator PR-50 Series is a compact pressure reducing regulator designed for accurate downstream pressure control in gas and liquid instrumentation, laboratory, analytical, and industrial process applications. The regulator provides stable outlet pressure regulation with excellent sensitivity, fast response, and reliable repeatability under varying inlet pressure and flow conditions. Its diaphragm-operated design ensures smooth throttling characteristics and dependable shutoff performance while maintaining a compact footprint for installation in confined systems.

The PR-50 Series is engineered for precision pressure control in low- to moderate-flow applications where stability, corrosion resistance, and long-term reliability are important. Standard construction materials include 316 stainless steel, brass, Monel, and Hastelloy configurations for compatibility with corrosive, toxic, oxidizing, and high-purity gases and liquids. Multiple seat and elastomer material options are available to optimize chemical compatibility, leakage performance, and service life.

Available configurations include multiple outlet pressure ranges, Cv flow capacities, threaded process connections, pressure gauge ports, panel mounting arrangements, and specialty clean-service options for analytical and semiconductor applications. The regulator supports both gas and liquid service while maintaining reliable control performance across a broad operating range.

Typical applications include gas analyzers, laboratory instrumentation, sample conditioning systems, semiconductor support equipment, calibration systems, gas distribution panels, chromatography systems, pilot plants, process skids, and industrial process installations requiring stable and reliable pressure reduction.
