pneumatically actuated ball valves and butterfly valves

We supply ball valves and gate valves with double-acting or single-acting pneumatic rotary drives. The actuators can be scanned with limit switch boxes. which are set above on the rotary actuator and connected via the NAMUR interface with it. The pneumatic connection is done either with hoses on the connection threads or through assembly of a NAMUR valve directly on the actuator. Through the gear rack design the rotary drives have a constant torque over the entire slewing range.
