Reducing bushes are indispensable components for the exact adaptation of actuator shafts to the stem of valves. They allow pneumatic and electric actuators to be mounted on butterfly valves and ball valves with different shaft profiles. Our reducing bushes are made of high-grade steel or stainless steel and are available in various sizes.
The variants shown are a selection of the forms that can be produced.
In combination with AirTorque actuators and accessories – matched to reducing bushes for actuators.
The right bush follows from the internal dimension of the actuator shaft and the stem dimension of the valve. State both dimensions and the bush can be determined unambiguously – a bush that is too large will not transmit the torque safely.
