Pump Valves are a quick way of isolating flow in a system. Flow is controlled through a quarter turn action which moves the hole in the ball inline or out of line with the flow, preventing or facilitating flow as appropriate. Our 22mm Ball Type Pump Valve has a convenient black handle for easy operation and is suitable for connecting to domestic central heating pumps.
