Reasons for using gate valves together with check valves
Thread Content
Dear experts, why are gate valves and check valves used together? Thank you all
This is not absolute. For example, most water pumps are equipped with check valves and gate valves at the pump outlet. For those with special needs, an electric valve is also installed in front of the gate valve. But the final valve must be a gate valve (or another type of valve). This valve serves two functions: controlling the flow rate at the pump outlet and preventing backflow of the system fluid. The first function is used in normal production, while the second function is employed when maintenance is required on the valves or equipment located before the valve. Therefore, the comprehensive conclusion mentioned in the title is not advisable; it should be understood by referring to the actual principles underlying its application. For reference.

This is not absolute. The function of a check valve is to prevent fluid from flowing in reverse (to stop the pump’s impeller from rotating in the opposite direction and to prevent fluid from leaking between pumps), whereas a gate valve is a type of valve suitable for use in industrial processes; it can also be replaced with other types of valves.
