Ductile Iron Pressure Reducing Valve (PRVs) are designed to regulate and stabilize downstream pressure in water distribution networks, firefighting systems, and industrial utilities. They ensure consistent pressure regardless of inlet fluctuations, improving system safety and efficiency. These valves comply with AWWA C530, EN 1074-5, ISO 9001, and BS standards, ensuring reliable performance. Ductile Iron Pressure Reducing Valve with FBE Coating Makes it perfect suit for SWCC & NWC Projects.

Applications

Ductile Iron Pressure Reducing Valves are essential in:

  • Municipal Water Distribution (NWC, SWCC projects)

  • Firefighting Networks (NFPA Compliant Systems)

  • Industrial Cooling & Utility Systems

  • Irrigation Networks

  • Desalination & Sewage Treatment Plants

These valves are available in Class 125/150, PN10–PN25, and 150–250 PSI ratings, ensuring flexibility across different projects. Their ability to maintain stable downstream pressure makes them vital for protecting pipelines, pumps, and connected equipment. For pipes check out Middle East Piping.

At GCC Valves, we deliver high-quality, tested PRVs with full documentation packages (MTCs, ITPs, performance tests) to meet the strict requirements of Aramco, ADNOC, SWCC, NWC, SABIC, and BAPCO projects.
