Two-way zone valves
Grundfos’ UP Two-Way Zone Valves for hydronic heating applications incorporate a 24-VAC, normally closed, motorized actuator that is removable with the push of a built-in button for easier installation and servicing. With its compact and installer-friendly design, the in-line actuator features a high gear ratio that eliminates gear-tooth stress, water hammer and valve bouncing for a virtually silent operation.
