Our actuating keys in accordance with DIN 3223 are the proven solution for reliable valve actuation. This standard defines the requirements for actuating keys and distinguishes between different types (A, B, C, E), which are characterized by different sizes and profiles of the square. This ensures that the right key is available for every fitting.

Actuating wrenches are mainly used to operate underground fittings via extension spindles. They are indispensable tools for utility companies, construction companies and the municipal sector.

Our product portfolio includes a wide selection of DIN 3223-compliant actuating wrenches - for above-ground and underground hydrants as well as for tapping bridges. All versions stand for durability, stability and classic handling.
