Caleffi Z151000 Z-One 24V Normally Closed Zone Valve Actuator with Auxiliary Switch, Terminal Block

The Caleffi Z151000 is a 24V normally closed actuator for Z-One zone valves, supplied with a terminal block for wiring.

It mounts on a Z-One valve body to open and close the zone on a thermostat call, and can be used to replace a failed actuator without draining the system. Normally closed means the valve stays closed until power is applied. The auxiliary end switch closes when the valve opens and can be used to signal a boiler, circulator or zone control. Rated for a maximum temperature of 240°F.

Before ordering, confirm your control voltage is 24V, that you need a normally closed actuator, and that the valve body is a Caleffi Z-One. The valve body is not included.
