Gates Valves

Gate valves are useful for fully open and fully closed service functions. Ideal for installation in pipelines as isolation components, the valve opens when lifting a gate out of the pathway of the fluid and closes when the gate returns to its position. However, they are not an appropriate component for controlling or regulating flow in valves.

Compact in design, gate valves require little space along the pipe axis and don’t restrict the flow when the gate is opened fully. They are also known as multi-turn valves and operate either clockwise to close or clockwise to open the rotating motion of the threaded stem.

Suitable for above-ground and underground installation, gate valves are useful in a wide variety of applications. Choosing the correct valve dependent on its application is vital, so there are no high replacement costs. Gate valves are often used when minimum pressure loss and a free bore are needed.

Generally, gate valves are used to completely shut off fluid flow or provide full flow in a pipeline. They are installed in pipelines as isolation valves and perform by moving clockwise to close or clockwise to open along the stem. They function in the fully closed or fully open positions and consist of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.
