What are the disadvantages of GATE?
The Main Disadvantages of Gate Valves
- Gate Valves Open & Close Slowly. During the opening process, the valve plate needs to be lifted to the upper part of the valve chamber.
- Gate Valves can be Prone to Scratches.

What are the advantages and disadvantages of SCR?
It can handle large voltages, currents and power. The voltage drop across conducting SCR is small. This will reduce the power dissipation in the SCR.
Which of the following is a disadvantage of ball valves?
Disadvantages of Ball Valves: Wear and tear: If the medium has suspended particles, it will cause the valve body and the ball valve to wear, and the valve may be stuck. Limited size range: Ball valve and a limited size range. Normally it could be 8 inches. If you need larger size we could customized for you.
What happens if I fail GATE?
If you are attempting GATE for the first time and you’ve failed to clear it with a good score, you can bet one more year on it provided your preparation strategy must be more robust and focused on clearing the examination in the second attempt. Re-attempt the exam with better preparation. Target getting into PSUs.
What is the disadvantages of SCR?
Drawbacks of SCR: It can conduct only in one direction. So it can control power only during one-half cycle of ac. It can turn on accidentally due to the high dv/dt of the source voltage. It is not easy to turn off the conducting SCR.
