- Q: Why the valve can only be fully open and fully closed valve can adjust the flow?
- Valve, if adjusted, it is easy to wash the sealing surface, resulting in sealing surface damage.
- Q: What kind of valve is gate valve? Is it different from the cut-off valve?

If you want to understand in detail, it is recommended to take a sample of valve manufacturers to see the internal structure.
- Q: Why does the centrifugal pump start and stop in the case of closing the gate valve?
- Centrifugal pump to close the gate valve in the case of the start: the centrifugal pump power increases with its flow rate, when the flow is zero (valve closed), the minimum power to operate. Start the valve off from the angle of the motor. If the valve is started, the motor itself to start the current is larger, coupled with the power of the pump is also large, easy to cause the motor over-current trip, serious will burn the motor.
