The GO Regulator PR-56 Series is a heavy-duty pressure reducing regulator designed for accurate downstream pressure control in high-flow gas and liquid process applications. The regulator provides stable outlet pressure regulation with excellent sensitivity, fast response, and reliable repeatability under varying inlet pressures and demanding flow conditions. Its diaphragm-operated design delivers smooth throttling characteristics and dependable long-term performance in continuous industrial service environments.

The PR-56 Series is engineered for applications requiring robust construction, high flow capacity, and corrosion resistance in harsh operating conditions. 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 applications. The regulator is suitable for both gas and liquid service while maintaining stable pressure control at elevated flow rates and operating pressures.

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