Description

Gate valves, also known as a sluice valve, are mainly used to intercept the flow in oil & gas and power generation plants. A gate valve features sealing surfaces between the gate and seats which are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired.

They are installed both onshore and offshore, in the cryogenic and water treatment services.
