Product Details
Product description
Swing check valve, also known as a one-way valve or check valve, its role is to prevent the media back in the pipeline. Opening and closing pieces by medium flow and power to open or close, in order to prevent the media back valve is called the check valve. Check valves are automatic valves, mainly for the medium one-way flow of the pipeline, only to allow the media to flow in one direction, in order to prevent the occurrence of accidents. This type of valve in the pipeline should generally be installed horizontally. Can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media. Mainly used in petroleum, chemical, pharmaceutical, fertilizer, power and other pipelines.

Storage and maintenance
1 the valve must be kept in a dry, ventilated room.
2 the storage period of the valve, the valve should be closed and fixed, both ends of the flange should be closed.
3 during the storage of the valve, the surface of the machine is easy to be removed.
4 long-term storage of the valve should be regularly checked, timely protection.
Installation and maintenance
1 the installation position of the valve is not limited, usually installed in horizontal pipeline, can also be installed in the vertical pipe or inclined pipeline, but it is convenient for maintenance.
2 must be carefully checked before installation, the valve plate is marked and consistent with the requirement and condition.
3 when installing, should check the inner cavity, remove the valve flap fixing device, try to check the sealing surface of the valve flap, and clean.
4.. Lifting the valve before, should check whether it has been tightening screw ring.
5 installation should pay special attention to media flow, should make the normal flow direction and the direction of the arrow on the valve body on the direction of the arrow is consistent, otherwise it will cut off the normal flow of the media.
6 when installing, tighten the connecting bolts evenly and symmetrically.
