A butterfly valve is a shut-off valve with a relatively simple construction. In closed position, the disc blocks the valve bore as in open position, the disc is turned to allow flow. A quarter turn takes the valve from fully open to fully closed position, oppositely, the butterfly valve allows for quick opening and closure. Butterfly valves can be used for a broad range of applications within wate...

Check valves are automatic valves that open with forward flow and close with reverse flow. The pressure of the fluid passing through a system opens the valve, while any reversal of flow will close the valve. Exact operation will vary depending on the type of Check valve mechanism. Most common types of Check valves are swing, lift (piston and ball), butterfly, stop and tilting-disk. Types of Check ...

Ball valves A Ball valve is a quarter-turn rotational motion valve that uses a ball-shaped disk to stop or start flow. If the valve is opened, the ball rotates to a point where the hole through the ball is in line with the valve body inlet and outlet. If the valve is closed, the ball is rotated so that the hole is perpendicular to the flow openings of the valve body and the flow is stopped. Types ...

Prohibit 1 Hydraulic test shall be carried out under Negative temperature during winter construction. Consequence: Due to the rapid freezing inside the pipe during the hydraulic test, the pipe freezes out. Measures: Try to conduct a water pressure test before winter construction, and after the test, blow the water clean, especially the water inside the valve must be removed completely, otherwise t...

Pneumatic valve is an actuator that uses compressed air to drive and operate the valve. Its opening and closing speed is relatively fast, and it is commonly used for quick two position cut-off. It can also be used to regulate flow. Due to its main reliance on air source for operation, it has high practicality in flammable and explosive situations, and can be used to control gases, liquids, oil pro...
