3S Multi-Turn Actuators

The 3S Multi-Turn Actuators The 3S multi-turn actuators have been constructed particularly for butterfly and ball valves with gears as well as for gate valves. The actuators are waterproof and installed directly into the ground beneath a standard street cap or a manhole cover by utilizing the patented 3S earth placement or alternatively flanged directly onto the valve according to EN ISO 5210. The valve can still be operated manually via a standard square-end on top of the actuator.

In any case, manhole or underground construction is not necessary. This makes retroactive automation of buried valves economically feasible.

3S AIG mobile

The mobile 3S mobile actuator is a powerful slider turning device. The intelligent 3S digital electronics revolutionize the maintenance of valves with 3S AIG XS.

The new development 3S AIG XS is clearly lighter and easier to handle than the previous model, 3S AIG, and covers the needs of network operators with small and medium nominal sizes. With the System Berliner Kappe® or load amplifier the placement of big valves without use of physical strength is possible.
