Gate/Globe/Check valve
Gate valve: A valve that controls the flow of fluid by lifting and lowering the gate. It is usually used in situations where the flow of fluid needs to be completely cut off.
Globe valve: A valve that regulates and cuts off fluid flow by rotating or lifting the valve disc. It is suitable for occasions where the flow needs to be adjusted or the pipeline needs to be completely closed.
Check valve: A valve that automatically prevents the backflow of fluid. It only allows fluid to flow in one direction. It is often used to prevent the reverse flow of the pump or the backflow of the medium in the pipeline.
