Three-way zone valve8

3ZV2 Series Zone Valves are ideal for flow control in hot and cold water HVAC systems. Zone valves are typically used in conjunction with a thermostat to control room temperature. The 3ZV2 is electrically driven to open and or close via a bidirectional motor. Units are available in 1/2″, 3/4″, 1″, and 1-1/4″ sizes with 24 or 120 VAC power supply. Easy to install, these units are direct replacements for competitor units. Manual override lever is easily accessible externally. Consult factory for 220 VAC power supply, optional auxiliary switches, and BSP or sweat connections.

3ZV2 models come in floating or modulating input types. Floating units are controlled directly from the thermostat and modulation units accept either a 4 to 20 mA or 0 to 10 VDC input. Modulating models include a motor time out feature that automatically turns off the motor after the full stroke of the valve to increase motor life. Featured in the 3ZV2 is a detachable actuator that is easily removable by a turn key allowing the valve body to be installed without the actuator. Actuator housing is constructed of fire resistant plastic.
