Speciality Valve is the prevalent Rising Stem Gate Valve Manufacturer in India. We supply to Kerala, Gujarat and Tamil Nadu. A rising stem gate valve is a simple yet complex mechanical device that controls the flow of liquids or gases through a pipeline or system. It is built up of a gate-like obstacle that is raised or lowered by a threaded stem, hence the name “rising stem.” When the valve is open, the gate is lifted to allow fluid or gas to flow through; when the valve is closed, the gate is lowered to close off the opening.This valve is recognized for its robustness and capacity to establish a secure flow control.
How does Rising Stem Gate Valve ?
A rising stem gate valve is a type of industrial valve designed for regulating the flow of fluid within a pipeline. The working principle of a rising stem gate valve involves the use of a threaded stem connected to the gate inside the valve body. The gate is a flat or wedge-shaped barrier that can be raised or lowered to control the flow of the fluid. When the valve is in the closed position, the gate is fully lowered, obstructing the passage of fluid. Conversely, when the valve is in the open position, the stem is rotated, causing the gate to rise out of the flow path, allowing fluid to pass through.
The key components of a rising stem gate valve include the valve body, gate, stem, handwheel (or actuator), and packing. The stem is threaded, and as it is rotated, it moves either upward or downward, directly raising or lowering the gate. This upward and downward motion provides a visual indication of the valve’s status, making it easy to determine whether the valve is open or closed just by observing the position of the stem. One advantage of the rising stem design is that it allows for a clear and visible indication of the valve’s position, which can be crucial for operators in industrial settings. Additionally, this design is often preferred in applications where a slow operation is desirable, as the rising stem provides a steady and controlled movement of the gate.
