Flap valves are used were removable connection of a suction hose to the tubing system is needed. The spring loaded flap is opened manually and the hose cuff is inserted into the valve body. On systems with auto start-stop demand, the flap valve should be equipped with a micro-switch. This will give a start-stop signal for vacuum producer control when the valve is opened and closed.
