The YDK KCH-16 swing check valve is a flanged check valve with a ductile iron body. It lets fluid flow in one direction only and closes automatically when the flow reverses. This protects pumps, critical equipment, and the pipeline from water hammer, avoiding damage to the system during operation.<\/p>\n

An Phu Thanh is currently the importer and distributor of YDK swing check valves in Vietnam. The product comes with complete CO and CQ documents and a 12-month genuine warranty.<\/p>\n

Introduction to the YDK KCH-16 swing check valve<\/h2>\n

The YDK KCH-16 swing check valve is designed with a disc attached to a hinge, seated at an angle on the seat inside the valve body. When the pump runs, the flow pushes the disc up and opens a path for the fluid to pass. When the pump stops, the reversing flow together with the weight of the disc pulls the disc back onto the seat, and the greater the pressure from behind, the more tightly the disc is pressed closed. The valve operates entirely by the flow itself, with no need for human intervention or for any added electrical power or controller.<\/p>\n
