By lifting a rectangular or round gate out of the path of the fluid, a gate valve is opened. The distinct feature of a gate valve is the sealing between the seat and gate is planar, so the gate valves are used often when it is required to have a straight-line flow along with minimum restrictions. The gate faces can form a wedge shape or they can also be parallel. Gate Valves are mainly used for permitting or preventing the flow of liquids, but typical gate valves must not be used to regulate flow unless they are designed specifically for that purpose. For their ability to cut through liquids, gate valves are predominantly used in the petroleum industry. For very thick fluids, a special type of valve is used for cutting through the liquid which is known as knife valves. The flow path is enlarged in a very nonlinear manner with respect to the opening percentage on opening the gate valve. This means that the flow rate will not change in line with steam travel. Again, a partially open disk has a tendency to vibrate from the fluid flow. Typical types of gate valves are designed for being completely opened or closed. When they are completely open, the typical gate valve comes with no obstruction in the path of flow which results in very low friction loss. You can find a wide range of styles and sizes of gate valves from us.
