A valve that lets you completely stop, but not modulate, the flow within a pipe
A valve with a gate-like disk that moves up and down at right angles to the flow when actuated by a stem screw and hand wheel. Gate valves are best for service that requires infrequent valve operation and where the disk is kept either fully open or closed.
1. A valve with a linear motion closure member that is a flat or wedge shaped gate which may be moved in or out of the flow stream. It has a straight through flow path. 2. A type of valve whose flow control element is a disc or plate that undergoes translational motion in a plane transverse to the flow passage through the valve body.
