Gate Valves

What is a Gate Valve?

A gate valve, also known as a sluice valve, is mechanism for lifting a gate/wedge out of the path of the fluid. It is typically used for on/off control, rather than flow regulation.

 

How does a Gate Valve work?

A gate valve typically has a hand wheel that spins. The spinning motion causes the internal gate valve wedge to completely retract into the valve body allowing full flow.
