The GO Regulator PR-58 Series is a high-flow pressure reducing regulator designed for accurate 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 high-flow operating conditions. Its heavy-duty diaphragm-operated design supports smooth throttling characteristics and dependable long-term operation in continuous industrial service environments.

The PR-58 Series is engineered for applications requiring robust construction, corrosion resistance, and stable pressure control at elevated flow rates and pressures. 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.

Available configurations include multiple outlet pressure ranges, high Cv flow capacities, threaded and flanged process connections, pressure gauge ports, panel mounting options, and specialty clean-service preparations for analytical and semiconductor systems. The regulator is suitable for both gas and liquid service while maintaining dependable pressure stability across a wide operating range.

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