Piston Gate Valve

Gate valves are used for full opening or full closing, as isolation valves, and not used as control valves.

The gate valve is closed (CTC) or opened (CTO) by rotating the valve stem clockwise, and the gate plate moves upward or downward through the valve stem thread.

Gate valves are suitable for applications requiring minimum pressure drop and a full-bore design. When fully opened, the unobstructed flow path ensures low pressure loss, and their full-bore configuration allows compatibility with pipeline pigging operations.

The gate valve adopts the multi-turn threaded stem operation, which requires multiple rotations to fully open and close. Its slow actuation effectively prevents water hammer effect.

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.
