Water Supply Stainless Steel Pressure Reducing Valve
Our stainless steel pressure reducing valves are professional one-way pressure regulating valves designed for water supply pipeline systems, adopting high-quality 304/316 stainless steel body and direct-acting diaphragm structure. They can automatically reduce high inlet water pressure to stable outlet pressure, effectively protecting pipelines, faucets, water heaters and other equipment from overpressure damage.
Featuring precision spring diaphragm sensing system, the valves can sense downstream pressure changes in real time, automatically adjust valve disc opening to keep outlet pressure constant with high regulation accuracy (error ≤8%). The threaded connection (BSPP/NPT) is easy to install, no need for extra filters or bypass pipes, saving installation space and cost.
With excellent corrosion resistance, non-toxic and hygienic properties, they are ideal for potable water, tap water, cold and hot water systems. Complying with ISO 9001, CE, WRAS standards, our valves support pressure adjustment range 0.1-1.0MPa, suitable for high-rise buildings, residential quarters, hotels, factories and other water supply scenarios. We provide customized sizes, pressure ratings and connection types to meet diverse project demands.
