ZHMIS-A1 Swing Type Check Valves Flanged End

The swing check valve is also known as a one-way valve or non-return check valve, It is used to prevent the backflow of the medium in the pipeline. The valve with an opening and closing flap to turn itself on or off by medium flow and strength to prevent the medium back is named a check valve. Check valves are automatic valves, primarily used on the conduit of the medium in one-way flow, only allowing the medium to flow in one direction to prevent accidents. This type of valve should generally be installed in horizontal piping.

ZHMIS-A1 Swing Type Check Valves Flanged End FAQs

Q 1. What is the Warranty Period of Your Check Valves?
A.

Generally, the warranty period is one year.

Q 2. What Are the Differences Between Swing Check Valves and Lift Check Valves?
A.

(1) The lift check valve is a valve that automatically opens and closes the valve clack depending on the flow of the medium itself to prevent the medium from flowing back. Swing check valve opening and closing parts rely on the flow and strength of the medium to open or close automatically to prevent the medium from flowing back. The valve is called a check valve.

(2)The function of the lift check valve is to only allow the medium to flow in one direction and prevent the reverse flow. The swing check valve prevents the medium in the pipeline from flowing back. The opening and closing part is a valve that opens or closes on its own by the flow and force of the medium to prevent the medium from flowing back.

(3)The swing check valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea. Lift check valves are not.
