Category: Ball Valve
A ball valve is a quarter-turn valve with a port ball that can be rotated in the pipe to prevent or allow fluid flow. The special design can achieve a certain degree of flow regulation. The main specifications include the number of ports, port configuration, port connections, valve size, and the materials that make up the body, valve seat, seal and stem packing.
From compressed air pipelines to high-pressure hydraulic system, ball valves are used at any place where fluid flow must be cut off. Ball valves can provide low head loss characteristics because the ports can accurately match the pipe diameter. The sealing performance of the ball valve is better than that of the butterfly valve, but the purchase and maintenance cost is higher. Usually, ball valves are driven by a lever that provides a visual indication of the valve status.
