A gate valve is a valve that opens by lifting a barrier know as a gate out of the path of the fluid. A gate valve is a multiturn valve meaning that the operation of the valve is done by means of a threaded stem. As the valve has to turn multiple times to go from open to closed position, the slow operation also prevents water hammer effects. Gate valves are designed for fully open or fully closed service. Gate Valves are generally installed as isolating valves, and should not be used as control or regulating valves. Gate valves are often used when minimum pressure loss and a free bore is needed. When fully open, a typical gate valve has no obstruction in the flow path. Total Valve Systems can offer Slab, Knife and wedge style gate valves.
