The GO Regulator DL-59 Series is a heavy-duty diaphragm-loaded pressure reducing regulator designed for precise downstream pressure control in high-flow 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 demanding flow conditions. Its rugged diaphragm-operated design supports smooth throttling performance and dependable long-term operation in continuous industrial service.

The DL-59 Series is engineered for applications requiring high flow capacity, corrosion resistance, and stable pressure control in harsh operating 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 service life.

Available configurations include multiple outlet pressure ranges, high Cv flow capacities, threaded or 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 reliable control performance at elevated flow rates and operating pressures.

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