What is the difference between the cut-off valve and the gate valve?
- When opening and closing, the valve core and valve seat sealing surface always contact and rub each other, so the sealing surface is easy to wear, the valve is close to shut down, the pressure difference between the pipe is very large, so that the sealing surface wear more serious.Gate valve and stop valve advantages and disadvantages:Valve is the advantages of small flow resistance, the media can flow in two directions, but there are tall, complex structure, sealing surface easy to wear shortcomings. The flow resistance of the gate valve is 3-5 times that of the gate valve. Open and close to shut down in order to seal the valve, the valve is completely closed when in contact with the sealing surface, the sealing surface wear is very small, because the flow of the main actuator with large valve should pay attention to adjust the torque control mechanism.s
