Dwyer Instruments ZV1032-NO | Two-way zone valve | 3/4" NPT | 120 VAC
Model ZV1032-NO For controlling the flow of hot and cold water in HVAC systems, zone valves are perfect. To regulate the temperature of a room, zone valves are usually used in conjunction with thermostats. The ZV1 is powered by electricity to open and closed by spring action. The units come with a 24 or 120 VAC power supply and are available in 1/2", 3/4", and 1" diameters. These units are exact replacements for competitor devices and are simple to install. The manual override lever is conveniently located outside. For information about the optional auxiliary switches, BSP or sweat connections, and 220 VAC power supply, contact the factory.
