Specialityvalve is the most trusted Rising stem gate valve manufacturer in India. The threads on rising stem gate valves are on the outside of the valve body. When the valve opens, the stem of the gate valve moves up. Non-rising stem valves are normally constructed of brass, bronze, or cast iron, whereas rising stem valves are typically made of cast or forged steel. The quantity of exposed stem on a rising stem gate valve makes it simple to determine whether the valve is open or closed.

Gate valve:

Gate valves are frequently used for many kinds of applications and can be installed above ground or underground. It is crucial to select the proper type of valve, especially for underground installations, to reduce the likelihood of expensive replacement costs.

Gate valves can be fully opened or entirely closed depending on the use. They should not be utilised as control or regulating valves because they are installed in pipelines as isolating valves. A gate valve is operated by spinning the stem in either a clockwise direction to close (CTC) or a clockwise direction to open(CTO). The gate travels upwards or downwards on the threaded portion of the valve stem as the stem is turned.

Gate valves with rising stems versus non rising stem

Rising stems, which are fastened to the gate and rise and fall together as the valve is opened and closed, allow for the lubrication of the stem and provide a visual indication of the position of the valve. The threaded stem is moved by a nut rotating around it. This kind should only be installed above ground.

The wedge inside the valve rotates using non-rising stems that are screwed into the gate. Since the valve stem is maintained inside the valve body, they require less vertical space. Specialityvalve sells gate valves with a valve position indication factory-mounted on the top of the stem. Both above-ground and underground applications are suitable for gate valves with non-rising stems.

Advantages:

1.    It's simple to open and close.

2.    Small fluid resistance, medium erosion and erosion seal the surface.

3.    Medium flow is not constricted, no turbulence, no pressure reduction.

4.    The sealing surface is easily worn and scraped, making maintenance difficult.

5.    A larger structure necessitates more room and a longer opening period.
