Why a check valve? Check valves are designed with the specific purpose of preventing flow from going the wrong direction. In the case of a swing check valve, this is done by allowing a swinging disk inside the valve body to swing open when liquid flows the correct way, but swing closed if there is any backflow. There is no handle for control, just the flow of the liquid. These are particularly useful in filtration and waste applications. Our metal swing check valves are produced by a top industry manufacturer. These brass and 316 stainless steel valves are premium quality with a screwed cap, integral seat, and NPT ends. We have worked out special relationships with manufacturers so that CIS can offer the best prices to our valuable customers. This includes our metal check valves.
