NRS Gate Valve

Our NRS Gate Valve, known fully as Non Rising Stem gate valve, has become the go-to isolation valve for buried pipelines and compact confined installation sites across global water and fluid infrastructure. If you compare it with OS&Y rising stem gate valves, you’ll notice the operating stem never extends upward outside the bonnet during opening or closing cycles. This compact structure drastically cuts vertical space demand, making it ideal for underground valve pits, wall-hidden piping and cramped mechanical equipment rooms.
We build our full lineup split by four major international specification systems: American MSS/AWWA standard, British BS standard, European DIN standard, all manufactured with robust cast iron or ductile iron bodies as standard build.
Every flanged NRS gate valve is engineered strictly to regional industry codes, with interchangeable face-to-face and flange dimensions for straightforward project retrofits and new build installs. These valves function solely as full open / full closed isolation equipment, not designed for flow throttling service.
