What is a Gate Valve ?
A Gate valve is a linear motion on-off or shut-off valve. The gate-valve comprises of a disc or wedge having two seating surfaces that come in contact with the valve seats to form a seal for stopping the flow. The pressure differential between the upstream flow direction and downstream side of wedge causes the wedge or disc to force against the downstream seat creating more effective sealing on the downstream side of the wedge. Gate valve is not used to regulate flow as erosion of disc and seat may cause leakage. A gate valve in partially open or closed position is also susceptible to vibration.
Where quick and frequent operation is essential use of quarter turn valves such as ball valves and plug valves must be considered.
