Non- rising stem gate valve manufacturers in India

Speciality Valve is among the most reputable Non- rising stem gate valve manufacturers in India that provides high-performance valves with a compact design, reliability, and suitability for applications with space limitations. Our valves are produced using high-quality materials and meet international standards to deliver efficiency and prolonged service life.

Why Required?

Non-rising stem gate valves are necessary in space-constrained vertical environments like underground pipelines or confined installations. They offer good shut-off performance without the need for extra clearance above the valve.

Key Parts of Non- Rising Stem Gate Valve:

Valve Body: Generally, made of cast iron, carbon steel, or stainless-steel construction

Gate/Disc: Moves vertically to seal or permit flow

Stem: Turns inside the valve body without rising externally

Bonnet: Encloses and shields the internal stem mechanism

Seat Rings: Give close shut-off to avoid leakage

Working of Non- Rising Stem Gate Valve:

In non-rising stem gate valves, the stem is internally threaded and does not vertically move beyond the valve body. When the handwheel is rotated, the stem turns within the gate, moving the gate upward or downward inside the valve to open or close the passage. This construction retains the motion of the stem as limited, and hence, it is best suited for small spaces.

Advantages of Non- Rising Stem Gate Valve:

Small structure, best for small spaces

Cost-effective and simple to install

Reliable shut-off with low leakage

Adequate for above-ground as well as underground installations

Lower exposure of stem to outside conditions
