NRS Gate Valve Manufacturer in India
Stem threads stay inside the bonnet — preferred for buried valves and low headroom.
NRS vs OS&Y
NRS keeps stem height constant (good for pits and buried service). OS&Y shows position via rising stem (good for fire-pump rooms). Many fire specs use NRS + post indicator underground and OS&Y above ground.

Frequently asked questions
What does NRS mean?
Non-rising stem — the stem rotates but does not rise out of the bonnet as the wedge opens.
Do NRS valves show open/closed?
Not by stem height; use a post indicator, position switch or window on the indicator post.
