Gate Valve an overview ScienceDirect Topics

Fig. 5.2 shows the internals of a Gate Valve that is half open. Figure 5.2. Gate valve. When fully open, a gate valve has no obstruction in the flow path and so has a very low pressure drop. If the fluid is very viscous a special type of gate valve known as a knife gate valve can be used.

Gate valve

A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid.Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The gate faces can be parallel but are most commonly wedgeshaped (in order to be able to apply pressure on the sealing surface).

How to Rebuild a Gate Valve DIY Guide for Piping

Gate valves are a simple valve that, unlike most other types of valves, do not depend on rubber gaskets to make a seal. Instead, they use guides and a quot;gatequot; made of metal to stop and start flow. The multiturn handle makes operation simple and smooth. Every so often, however, it may help to know how to rebuild a gate valve. Problems with gate valves are not common, but the one seen most often

Valve

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.Valves are technically fittings, but are usually discussed as a separate category.In an open valve, fluid flows in a direction from higher pressure to lower pressure.

Details of the gate valve internals and valve body and

Internals in the gate valve. The internals in the gate valve have a stem, a disc seal area, a seat and an upper seal (if any). The inner material of bronze and brass valves is usually the same as that of the valve body and bonnet.
