The industrial gate valve refers to a valve in which the closing part (gate) moves in the vertical direction of the center line of the passage. The gate valve can only be used for full opening and full closing in the pipeline, and cannot be adjusted and throttled. The gate valve is a kind of valve w
Typically, lift check valves are automatic valves that open under the pressure of fluid in one direction and act to prevent flow when the fluid flows in the opposite direction. The valve flap of the lift check valve is on the sealing surface of the valve seat, and its valve can be automatically raised and lowered.
Lifting check valve: The check valve sliding along the vertical center line of the valve body. The internal thread check valve can only be installed on the horizontal pipe.
The valve flap of the swing check valve rotates around the rotating shaft. Its fluid resistance is generally smaller than that of the lift check valve, which is suitable for larger diameter applications.
The valve flap of the swing check valve is disc-shaped and rotates around the shaft of the valve seat passage. The flow passage is streamlined and the flow resistance is smaller than that of the butterfly check valve. It is suitable for low flow rate and irregular flow.
