On which process valves (ball valves, butterfly valves) can the Copar be mounted?
The quarter turn actuator Copar is compliant with the ISO 5211 standard, which defines the interface between quarter turn actuator and process valve. The standard defines two attributes: • Hole circle diameter and hole diameter for the mounting screws used for mounting the actuator on the valve • Shape and dimensions of the mechanical connection between the valve and actuator shafts To be able to select a quarter turn actuator for a particular process valve, both the flange size and the square size must be known. With the square, you also need to check whether the pipe runs parallel or is turned 45°.
