RISING STEM GATE VALVE MANUFACTURERS IN INDIA

Speciality Valve is one of the prominent Rising stem gate valve manufacturers in India, supplying precision-engineered valves that are capable of delivering maximum flow control across a range of industries. Our rising stem gate valves are designed to last long, operate simply, and perform at high pressure and temperature for the long term.

Why Required?

Rising stem gate valves are used where a positive indication of the valve’s position is necessary. Rising stem gate valves provide visual proof of the opening and closing of the valve and are highly suitable for critical industrial pipeline operations where this visibility is crucial.

Key Components of Rising Stem Gate Valve:

1) Body: Cast in cast iron, carbon steel, or stainless steel
2) Gate/Disc: Operates vertically to control flow
3) Stem: Threading stem that extends with the gate to signify open/close position
4) Bonnet: Envelops the upper part of the valve and the stem
5) Seat Rings: Make a close seal on the disc

Working of Rising Stem Gate Valve:

When the handwheel is rotated, the stem travels upward along with the gate, opening the gate out of the flow path to allow maximum fluid flow. When the handwheel is rotated in the reverse direction, the gate is dropped, closing off the flow. The rising stem mechanism allows easy visual examination of the position of the valve.

Advantages of Rising Stem Gate Valve:

1) Easy position indication
2) Low pressure drops when fully open
3) Good shut-off force
4) Use in high-pressure systems
5) Long life
