Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns the valve will close to protect the piping, other valves, pumps etc.

As a safety device, the check valve is important when there is separation between an area of high pressure and one of low pressure. One such circuit is the accumulator, which often employs the use of two check valves.Check valves are a type of valve that allows liquids, gases, and steam to flow in only one direction. A check valve can have a ‘stopping’ mechanism that can be shaped like a ball, disc, piston, or poppet.For additional information regarding the product, please contact with Dubuy support team.
