Can the ball valve drive units type VZPR replace the previous (no longer available) type (CR)QH-DR units?
The ball valves of the VZPR units have exactly the same dimensions as the ball valves of the (CR)QH-DR units up to sizes 1/4″ and 3/8″ (brass design) and 1/4″ (stainless steel design). That ensures their replaceability by the VZPR units. The installation dimensions of the pneumatic actuator, however, differ from those for previous actuators, but in most applications the dimensions of the ball valve will be the decisive factor.
