Product Description
The low temperature check valve refers to a valve that automatically opens and closes the valve flap depending on the flow of the medium to prevent the medium from flowing backward. Check valve belongs to an automatic valve, and its main function is to prevent the medium from flowing backward, to prevent the pump and the drive motor from reversing, and to release the container medium. Check valves can also be used to supply lines to auxiliary systems whose pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

Notes When Use
1. It should ensure that the pipe is blown clean before installation.
2. When installing, make sure that the flow direction indicated by the arrow on the valve body should be consistent with the flow direction of the fluid.
3. This valve has been degreased. Store and keep clean when installing.
4. After the pipeline construction is completed, all the valves on the pipeline should be opened, and the residue in the pipeline should be thoroughly and thoroughly kept to ensure that the pipeline system is clean and free of debris.
5. The installation system diagram with the oil-free requirements should be degreased.
6. Slowly open and close during use.
7. If the precision parts such as the valve disc, valve seat and valve stem are worn or damaged, it must be repaired and replaced in time.
8. For parts such as gaskets and sealing materials, replace them with new ones each time.
