Can the CR-QH-DR ball valve actuator be replaced with the Copar?
The Copar and the quarter turn actuator of the CR-QH-DR both work according to the rack & pinion principle and are therefore fully compatible. However, the CR-QH-DR is only available as a double-acting quarter turn actuator, so it can only be directly replaced by the double-acting Copar DRD. The quarter turn actuator of the CR-QH-DR is identical to that of the QH-DR. The Festo designation “CR” for increased corrosion resistance refers only to the three-part ball valve made from stainless steel. If the actuator used in the application also needs to be highly corrosion resistant, the Copar with increased corrosion resistance “C” should be used.
