| product features |
| A check valve refers to a type of valve whose opening and closing components are circular and act to block the backflow of the medium by relying on its own weight and medium pressure. Usually, this type of valve operates automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the flow is cut off by the fluid pressure and the self closing valve disc of the valve acting on the valve seat. |
