ValvesOnly is the leading Rising Stem Gate valve manufacturers in USA. These valves provide secure flow management, carefully adjusting the movement of liquids or gasses in pipelines and systems.
What is rising stem gate valve?
To ensure precise flow management and security in numerous industrial settings, the valve features a stem that moves vertically when the gate is either opening or closing.
When the valve is fully opened, the stem stands straight; when it is fully closed, it drops, giving instant visual evidence. This design is extremely beneficial in isolated applications, particularly in high-pressure, large-diameter lines where reducing pressure drop is essential. Its exposed threading further improves practicality by making lubrication simple.
A threaded stem that is attached to the gate inside the valve body is what drives the valve's function. The gate can be wedge-shaped or flat, and it can move up or down to control the flow of fluid. When the gate is closed, it completely blocks the flow of fluid; when it is open, the stem rotates to raise the gate and let the fluid through. The valve body, gate, stem, handwheel or actuator, and packing are important parts. In industrial settings, the stem's movement directly lifts or lowers the gate, providing operators with an important visual indication.
Difference between rising stem gate valve and non rising stem gate valve?
Rising Stem Gate Valve: The position of a rising stem gate valve is clearly visible due to its stem moving up and down when the valve is operated. Used in the applications like large-diameter pipelines and high-pressure systems, where precise flow control and isolation are essential, benefit from this design. Operators can quickly determine if the valve is open or closed by observing the vertical movement of the stem, which directly reflects the position of the gate. However, in situations where buildup of debris is likely, this specific valve could be at a higher risk of getting damaged and requires sufficient vertical clearance above the valve for the stem to move.
Non Rising Gate Valve: A non rising stem gate valve, on the other hand, maintains the stem in place as the gate rises or falls to control flow. Because of its compact shape, they can be used in tight spaces or underground installations where vertical space is limited. Non-rising stem gate valves are more resistant to debris damage and generally need less maintenance due to their simpler design, despite potentially requiring additional means to confirm valve position, like handwheels or actuators for external indications.
