LÜDECKE ball and throttle valves are used as shut-off valves in pipe systems.
In ball valves, a ball serves as shut-off device in the fitting. It opens and closes the fitting with a 90-degree rotation. Due to the full passage only small losses of flow occur. Specific O-rings which are attached between the ball and the body provide sealing.
In throttle valves, a cone shaped throttle will be pressed against the body under pressure. In this way, the valve seals without any seal wear (almost no dead space in the passageway). When turning off, pressure is reduced by ventilating the output side. This allows for safe disconnection.
