The Copar and the quarter turn actuator of the QH-DR work according to the rack & pinion principle and are therefore fully compatible. However the 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. Please note the interfaces for the ball valve (flange and square) and the torques.
