Caleffi Z54P Z-One 2-Way Zone Valve, Normally Closed, Terminal Block with Micro Switch, 1/2" Press, 2.5 Cv, 24V

The Caleffi Z54P is a Z-One 2-way motorized zone valve with a normally closed 24V actuator with screw terminal block and auxiliary micro switch (end switch), assembled on a 1/2" press valve body.

Z-One zone valves open and close individual zones in hydronic heating systems on a call from a 24V thermostat or zone control. The end switch closes when the valve opens, so it can be used to enable the boiler or zone circulator. Field wiring lands on a screw terminal block on the actuator. The press-connection body installs with a copper press tool, with no soldering at the valve. This model is rated for a 2.5 Cv flow capacity and a maximum fluid temperature of 240°F.

Before ordering: confirm that the 1/2" press connection matches your piping, that the control circuit is 24V, and that the zone valve is meant to stay closed without power (normally closed).
