Zone valves are used to control hot and chilled water in heating and airconditioning systems. Coupled with a thermo-electric control actuator and controlled by a room thermostat, they allow automatic on/off control of the hydronic circuit. The 6762 series Twistop™ and 6767 series Twistop+™ are available with sweat union, press union and PEX expansion union connections. The union nut makes installation and maintenance fast, easy and efficient for a variety of end connection tailpiece options. The 676000A and 676500A valve bodies have 1” thread for field instaling any of 5 end connections styles in sizes 1/2”, 3/4” and 1”. Choose between two styles of thermo-electric actuators with, or without, auxiliary micro-switch: The TwisTop actuator, code 6563x4, featuring a pop-up opening/closing indicator which can be manually opened with a twist of the top; or the code 6564x4 with pop-up opening/closing indicator, and quick-coupling for easy installation. Both styles have low inrush current draw and power consumption. Separately orderable valve bodies, actuator styles and end connections, allows field assembly of the desired zone valve without compromise.
