Stop-Check Valve

A stop-check valve is a type of valve that combines the functions of a stop valve and a check valve. It is designed to allow fluid flow in one direction while preventing backflow in the opposite direction.

The stop function of the valve allows the user to manually control the flow of fluid by opening or closing the valve. This is useful for situations where the flow needs to be completely shut off, such as during maintenance or repairs.

The check function of the valve prevents backflow by automatically closing when the flow direction reverses. This helps to prevent damage to equipment or systems caused by the reversal of fluid flow.

Stop-check valves are commonly used in applications where both flow control and backflow prevention are required, such as in water supply systems, steam systems, and oil and gas pipelines. They are available in various sizes and materials to suit different applications and operating conditions.
