How to maintain the check valve?

1. The check valve should be stored in a dry and ventilated room to prevent moisture, rain and rust.

2. The opening and closing parts of check valve should be in the closing device during storage or transportation, and the following work should be done at the same time:

    a) The disc should be fixed in the open position.

    b) The inner ports at both ends of the diameter are blocked with foam plates, and the ports must be plugged tightly with stuffed caps to prevent dust and rust, keep the channels clean and the end faces flat.

    c) The check valve should be stable when placed and not be squeezed by each other.

3. The check valve should be checked regularly when it is placed for a long time. Every three months, check the dirt and rust on the two channels, the sealing surface, and the protection status of the welded joint. After wiping the dirt and rust, repaint the anti-rust oil for protection
