Caleffi Z55 Motorized Zone Valve

The Caleffi Z55 Motorized Zone Valve delivers precise zone control for heating and cooling systems. This 2-Way valve, with a 3/4 inch nominal size, uses soldered end connections and a spring-return electric actuator for reliable, automatic operation.

Designed for hot and chilled water applications, it features a brass body, stainless steel stem, EPDM seal and paddle, and a machined brass seat for tight shutoff. The valve is normally open (NO) and offers fast timing with 60 seconds to open and 6 seconds to close, making it ideal for modern HVAC setups. It operates on 24V AC at 50/60 Hz (0.4 A) and handles up to 300 PSI. With a flow capacity of 7.5 CV and a compact push-button mounting, it's ready for simple integration into your control system.
