How does it work: Gate Valves

Gate valves are the most common valves found in the distribution system. Gate valves are mostly used for the on/ off control. Gate valves prevent the flow of the liquid in both directions. They are very easy to install and to maintain. Gate valves are cost-efficient and they are mostly used in petroleum industries because of their abilities to cut through liquids. 

What is a Gate Valve?

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 principle part of this particular valve which can connect the inlet and outlet pipes in a piping system. 

What are the different applications of Gate Valves?

Mainly it is used for all kinds of applications and it is the best fit for all types of above ground and underground applications.

  • It is mostly used when the pressure loss is minimum and when the free bore loss is needed.
  • It can be used for numbers of fluids and it is suitable for potable water, wastewater and neutral liquids 
  • The temperature is required between -20 and + 70-degree centigrade for which the velocity of the flow should be 5 m/s and up to 16 bar differential pressure. 

 

What is the working principle of the Gate Valve?

There is a handle wheel on the top of the gate valve and when this wheel will be rotated in a clockwise direction, the steam and gate will move in the downward direction. It prevents the leakage of fluid through the valve.

When the wheel is rotated in the anti-clockwise direction, the valve will be opened and the steam and gate will move in the upward direction across the fluid. The gate valve can also be used in the semi-opened direction but the erosion of gate as fluid will strike and hence it is not recommended to open it partially.

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.
