Gate Valve Types

The parallel gate valve uses a flat disc gate between two parallel seats upstream and downstream.

Gate valve types.

The gate faces can be parallel but are most commonly wedge shaped in order to be able to apply pressure on the sealing surface. Solid hollow split and flexible wedge. When the gate valve is fully open the disk of a gate valve is completely removed from the flow. A gate valve is the most common type of valve used in any process plant.

The mechanical device that controls the flow and pressure within a system or process is called valves and there are many types of valves such as gate valve globe valve ball valve etc. Gate valves can be divided into two main types. The familiar outdoor spigot for a garden hose offers an example of a gate valve. They are essential components of a piping system that conveys liquids gases and vapors etc.

Their mechanism usually involves a round knob that when turned lowers or raises an internal gate or wedge to control the water flow rate. Two basic types of gate valves are the manufactured wedge type and the double disc type and there are several variations within each of these types. It s a full opening closing valve. Therefore virtually no resistance to.

A third type of gate valve called conduit valve is shown in fig. Gate valves are usually divided into two types. Gate valve is a linear motion valve used to start and stop the flow of fluid. Gate valves are used in almost all fluid services such as air fuel gas feedwater steam lube oil hydrocarbon and all most.

Shut off is obtained by the free floating seat or disk gate allow the upstream pressure to seal the seat and disk against any unwanted seat leakage. The solid wedge is a single piece solid. Valves can be categorized into the following types based on their operating mechanism. A gate valve is the most common type of valve in any process plant.

There are four types of wedges. In service these valves are either in a fully open or fully closed position. There are many types of gate valve. It is a linear motion valve used to start or stop fluid flow.

In service these valves are either in a fully open or fully closed position. 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. Ball valve for on off control without pressure drop ideal for quick shut off since a 90 turn completely shuts off compared to multiple 360 turns for other manual valves.
