Reducing sleeves are indispensable components for the exact adaptation of drive shafts to the stem of valves. They enable pneumatic and electric actuators to be mounted on butterfly valves and ball valves with different shaft profiles. Our reducing sleeves are made of high-quality steel or stainless steel and are available in various sizes.
The variants shown are a selection of the shapes that can be produced.
In combination with AirTorque actuators and accessories for maximum efficiency and reliability.
