Pneumatically operated ball valves & flaps

We supply ball valves and butterfly valves with double-acting or single-acting pneumatic rotary actuators. The drives can be sensed with limit switch boxes that are placed on top of the part-turn drive and connected to it via the NAMUR interface. The pneumatic connection is made either with hoses on the connection threads or by installing a NAMUR valve directly on the drive. Thanks to the rack and pinion design, the rotary drives have a constant torque over the entire swivel range.
