A gate valve is a linear motion valve that is used to start or stop the flow of the fluid in piping. There is a gate or wedge type disk which moves perpendicular to the flow which directs the flow to stop or start. In any process plant, the gate valve has the most common use and are suitable for both above-ground and underground installations. A gate valve is also known as a sluice valve. It is very easy to open it, one just have to lift the gate out of the path of the fluid. It does not require a wide surface; it fits in a very little space along the pipe axis. It requires a 360° surface contact between disk and seat to achieve proper sealing. A Gate valve is made up of certain parts that allow it to function properly. Valve’s body or shell is the most principal part of this particular valve which can connect inlet and outlet pipes in a piping system. Some other parts of a gate valve are as followed. Bonnet, Solid Wedge, Body seats, Stem, Back seat, Gland follower, Gland flange, Stem Nut, Yoke Nut, Handwheel, Hand wheel nut, Stud bolts, Nuts, Bonnet Gasket, Lubricator, Packing. All these parts allow the Gate & sluice valve to function properly.
Now let’s discuss the main types of gate valves.
1. Knife Valve
Knife gate valves contain a very high quantity of suspended liquids. It is mainly used for on – off and isolation services in systems. Knife valves are the best suitable for working in some of the harshest environment. These valves should be used for the applications which require a completely open or completely closed position.
2. Brass Gate Valve
Brass gate valves are the perfect fit for the applications where corrosion is a serious concern. It is considered as the most durable gate valve. It has a very high capacity to tolerate high temperatures as well as high pressure.
3. Slide Gate Valves
The main purpose of the slide gate valve is to shut off the flow of product from discharge points such as dry bulk storage bins, silos, conveyors, etc. It is the best choice for industrial works.
4. Non-return Valves
Non-return valve has considerable use in allowing the liquid as well as gas to flow in one direction. It is widely used in a huge variety of applications and household items.
5. Check Valves
Check Valve has a very vast use in a variety of applications. It is also used in household items. Mostly check valve has two ports. One for fluid to enter and other for the fluid to leave. Check Valves & Non-return Valve are available in a variety of sizes and cost as well.
