The lateral valves are solenoid valves with two or three connections and two switch positions in the basic position closed (NC).
In this type of construction, the magnetic drive is not arranged coaxially, but laterally. Additionally, this valve construction is not pressure-balanced, and the switchable pressure range is therefore significantly smaller than with valves in a coaxial design. However, the lateral design is often sufficient for applications in the low-pressure and rough vacuum range and, thanks to its simple construction, also offers a very attractive price. Lateral valves are particularly well-suited to the packaging, glass, metal, and furniture industries as a robust and fast switching valve for lifting tools (suction cups). Since they do not require dynamic seals, they are ideally suited for rough use in a dusty environment. They are therefore also recommended for use in vacuum furnaces.
The DRV series (three-way valve) is a valve with three connections and two switching positions. The DRVs are the classic valves for vacuum lifting tools. Depending on the connection of the suction device and vacuum pump to the valve, the keep product de-energized and vent product de-energized functions can be activated. This assignment determines whether a heavy or even valuable load might come loose from the lifting tool in the event of a voltage or power failure. The DRV series is available in a nominal width of 12 to 25 mm and is not suitable for liquid media. Due to its design, pressure is limited to 2 bar.
The RSV series (tube seat valve) is a valve with two connections and switching positions, as well as the basic positions NC + NO. This classic open/close version is available in a nominal width of 12 to 50 mm and can be used for rough vacuum as well as for gaseous and liquid media. Due to the design, pressure is limited to a maximum of 10 bar.
