Piston Gate Valve

Gate valves are designed for fully open or fully closed service. They are installed in pipelines as isolating valves, and should not be used as control valves.

Gate valves are often used when minimum pressure loss and a free bore is needed. When fully open, a typical gate valve has no obstruction in the flow path resulting in a very low pressure loss, and this design makes it possible to use a pipe-cleaning pig.

Operation of a gate valve is performed doing a neither clockwise to close(CTC) or clockwise to open(CTO) rotating motion of the stem. When operating the valve stem, the gate moves upwards or downwards on the threaded part of the stem.

A gate valve is a multi-turn valve, meaning that the operation of the valve is done by a threaded stem. As the valve has to turn multiple times to move from open to closed position, the slow operation also prevents water hammer effects.

Product Introduction

The valve seat of the wedge gate valve has an integrated valve seat or a separate valve seat to select. The separate valve seat can be easily repaired in the later stage.

Product Advantages

Gate valves are generally found in pipeline systems and in applications where frequent shut off is not required. Large water supply lines use gate valves due to their straight flow path and less flow restrictions.

Gate valves are used for application with slurries and viscous media because they are easy to clean and maintain.

Gate valves are used in power plants, mining and water treatment applications which are in high temperature and high-pressure environments.
