The GO Regulator PR-59 Series is a heavy-duty pressure reducing regulator designed for precise downstream pressure control in high-flow gas and liquid process applications. The regulator delivers stable outlet pressure regulation with excellent sensitivity, fast response, and reliable repeatability under varying inlet pressures and demanding operating conditions. Its robust diaphragm-operated design supports smooth throttling performance and dependable long-term operation in continuous industrial service.

The PR-59 Series is engineered for applications requiring high flow capacity, pressure stability, and corrosion resistance in harsh process environments. 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 services.

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 reliable pressure stability at elevated flow rates and operating pressures.

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