A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.
What Is a Gate Valve Used For?
A gate valve is a valve that opens by lifting a gate out of the path of the fluid. The major advantage of a gate valve is that it can be fully opened or closed with a very small movement of the gate.
This allows for quick operation of the valve. Gate valves are widely used in industries such as oil and gas, water treatment, power generation, and more.
Gate valves are classified into two major types: rising stem and non–rising stem. A rising stem gate valve has a stem that rises as the gate is opened.
This type of valve is well suited for applications where it is important to know the position of the gate. A non–rising stem gate valve has a stem that does not rise as the gate is opened.
This type of valve is often used in applications where space is limited. Gate valves are available in a variety of materials, such as cast iron, ductile iron, steel, bronze, and more.
The material selection is based on the service conditions, such as temperature, pressure, and fluid compatibility. Gate valves are used in a variety of applications, such as oil and gas production, power generation, water treatment, and more.
