what is gate valve? a gate valve can be defined as a type of valve that used a gate or wedge type disk and the disk moves perpendicular to flow to start or stop the fluid flow in piping. a gate valve is the most common type of valve that used in any process plant. it is a linear motion valve used to start or stop fluid flow. in service, these valves are either in fully open or fully closed

gate valve: solid or flexible wedge. 2010-10-22. be however aware of flow speed limitations, which is commonly lower for the soft sealing gate valve. also: depending on your stone and total application requirements, other type of valves than gate valves could be considered, again also depending mainly on pressure class and size.
therefore, the head loss of the valve is small and provide a high flow rate capacity. soft or metal to metal sealing design are available with different wedge configurations such as solid wedge, flexible wedge or with an splitted configuration wedge in order to meet the specific service conditions.
the wedge shape also results in a seal on both sides of the gate. since the disk is in contact with the seats only when the valve is closed, the wedge gate valve offers a maximum resistance to wear, where turbulent flow is present.
