butterfly valves

These valves are available either as between flange valves (with large holes for flange screws, are clamped between 2 flanges) or as butterfly valves (with female threads, is screwed onto a flange). You have the choice between collar materials (EPDM, NBR or FKM), disc materials (stainless steel or grey iron casting) and housing materials (grey iron casting or stainless steel) and can thus select the valves individually for the flowing medium. The butterfly valves are either activated manually via a handle/a gear or via a pneumatic rotary actuator and can also be operated in a middle setting (e.g. half opened).
