| New Zone Valves from Dwyer Instruments The new Series ZV1 and 3ZV1 Zone Valves are perfect for use with temperature controllers and thermostats to control temperature in HVAC systems. The valves control the flow of hot and cold water in the HVAC system thereby controlling temperature. Units come in two-way and three-way constructions and are spring return normally closed. They feature a direct-coupled actuator design and are available in ½", ¾ and 1" sizes. Zone valves incorporate manual overrides, and are for use with supply voltages of 120 VAC, 24 VAC, or 230 VAC. write your comments about the article :: © 2007 Construction News :: home page |
