A Ball Check Valve consists of a threaded or flanged body with internal features that guide a rubbercoated ball in and out of the seat as the flow goes forward and reverse.
Due to its simple flow efficient and virtually maintenance-free design the valve is. Depending on the valve and trim we can achieve temperatures in excess of 1000F for metal seated ball valves. Ball Checks Ball check valves use a ball inside the body to control the movement of flow. A floating design ball valve sandwiches the hollow ball between two or more cupped seats that form a tight seal between the body and the ball at the inlet and outlet ports of the valve body. A Ball Check Valve is a simple and reliable valve with the only moving part to block the reverse flow is a spherical ball. This feature makes ball checks useful for viscous media.
