Specialityvalve is the most trusted Rising stem gate valve manufacturer in India. Rising stem gate valves have threads that are located on the exterior of the valve body. The gate valve's stem rises when the valve opens. Rising stem valves are often made of cast or forged steel, while non-rising stem valves are typically made of brass, bronze, or cast iron. A rising stem gate valve's amount of exposed stem makes it straightforward to tell whether the valve is open or closed.
Gate valve:
Gate valves can be put above ground or underground and are often utilised for numerous applications. For underground installations in particular, choosing the right kind of valve is essential to lowering the possibility of high replacement expenses.
Depending on the use, gate valves can be fully opened or completely closed. Because they are put in pipelines as isolating valves, they should not be used as control or regulating valves. The stem of a gate valve is rotated either clockwise to close (CTC) or counterclockwise to open (CTC) (CTO). As the valve stem is turned, the gate moves up or down on the threaded portion of the stem.
Difference between rising stem gate valve and non rising stem gate valve:
Rising stems provide for the lubrication of the stem and offer a visual indication of the position of the valve. They are attached to the gate and rise and fall together as the valve is opened and closed. A nut that revolves around the threaded stem moves it. Only aboveground installations of this nature should be made.
By use of non-rising stems that are fitted into the gate, the wedge inside the valve spins. They take up less vertical space since the valve stem is kept inside the valve body. Gate valves with a valve position indicator factory-mounted on the top of the stem are available from SpecialityValve. Gate valves with non-rising stems are appropriate for both above-ground and underground applications.
Advantages:
1. It's easy to open and shut.
2. The surface is sealed by mild fluid resistance, moderate erosion, and erosion.
3. There is no pressure loss, no turbulence, and no restriction of the medium flow.
4. The sealing surface is easily scraped and damaged, which makes maintenance challenging.
5. A bigger building requires more space and a longer opening period.
