Gate valves are widely utilized in many different applications and can be underground or put below ground. It can be used in fully closed or fully open mode. So here this article gives the advantages and disadvantages of gate valves to better understand this topic.
Benefits or Advantages of Gate Valve
- It is inexpensive and has good valve rigidity.
- Simple design and low flow resistance.
- The closing features are very good for this valve.
- Gate valves offer superior sealing performance.
- It is easy to maintain and disassemble.
- It is good manufacturing technology.
- It takes very little torque to open and close.
- Installing it is simpler than installing other kinds of valves.
- The fluid resistance of gate valves is minimal.
- It can provide a larger flow capacity than a ball valve.
- installs more easily than other kinds of valves.
- They provide laminar flow, and the pressure loss is minimal.
- It works well with viscous liquids and slurries.
- There are two flow directions for gate valves.
- It is good manufacturing technology and a wide range of technology.
- The length of the structure is relatively short.
- Applications requiring zero leakage can be used it. It can be used for the most typical industrial uses, such as processing chemicals, gas, water, and oil.
- This valve can be used both ways in the circuit.
Drawbacks or Disadvantages of Gate Valve
- It is difficult to repair and operate because it requires a lot of torque to open and close.
- Prone to scratches and Poor throttling characteristics and not used for throttling conditions.
- The opening height and overall dimension are relatively large, which requires a large installation space.
- Both the entrance height and shape size are greater.
- The gate valve opens and closes slowly.
- It is complex and sensitive with many moving parts and seals.
- This valve can require regular calibration.
- It can be time-consuming and costly.
- Have high-pressure drop. The valve stem may not be strong enough to withstand high pressure and may break.
- The more parts, the structure is more complex.
- It's harder to manufacture and maintain.
- Gate valves can be difficult to place, making it difficult to achieve a good seal.
- Gate valves are more expensive than ball and butterfly types of valves. Because it requires more manufacturing materials.
- A gate valve's susceptibility to corrosion damage is another problem. This is a result of the metal used to make gate valves, which corrodes when exposed to liquids like water. This could lead to a leak or even the valve failing.
- Another disadvantage of gate valves is that they can become stuck. so it can be difficult to open or close the valve, long time to open and close. causing difficulties in the piping system.
