Caleffi Z45P Z-One 2-Way Zone Valve 3/4" Press, 24V Normally Closed with Auxiliary Switch, 7.5 Cv

The Caleffi Z45P Z-One is a 2-way, normally closed motorized zone valve with 3/4" press connections, a 24V actuator and an auxiliary end switch.

Z-One zone valves control flow to individual heating or cooling zones in hydronic systems. The valve stays closed until the thermostat calls, and the end switch can signal the boiler or circulator. The valve has a flow capacity of 7.5 Cv and a maximum close-off differential of 20 psi, and is rated to 240°F. The actuator can be removed from the body for service.

Before ordering, confirm the 3/4" press connection, the 24V control voltage, and that your system differential pressure stays below 20 psi.
