All copper one-way check valve, also known as a backflow valve, check valve, pressure valve, or one-way valve, operates automatically based on the force generated by the flow of the medium in the pipeline. This type of valve is an automatic valve. Check valves are used in piping systems primarily to prevent backflow of the medium and to release media from within containers. They can also be used on pipelines supplying auxiliary systems where the pressure may rise above that of the main system.

Function: prevent the backflow of medium (such as water), ensure that the medium only flows in one direction, and prevent the water hammer, pressure fluctuation or equipment damage caused by backflow. The full copper material makes it corrosion resistant and high temperature resistant, suitable for cold water, hot water and some industrial media.

Product features

All copper valve body: corrosion resistant, suitable for drinking water system.

Rapid closure: Spring assisted structure prevents backflow and water hammer.

Low flow resistance: optimized design to reduce head loss and improve system efficiency.

Flexible installation: can be installed horizontally or vertically to adapt to different pipeline layout.

application scenarios

Pump outlet: prevent water from flowing back and damaging the pump body when the pump is stopped.

Water supply pipe network: water supply system for high-rise buildings and living areas.

Industrial pipeline: unidirectional flow control in chemical industry, sewage treatment and other fields.

Maintenance recommendations:

Check the sealing performance regularly to prevent valve disc from sticking.

When the medium contains impurities, it is recommended to install a filter.
