Zone ValveZone Sentry™ now easily handles chilled-water applications. The valve excels in situations where condensate could be an issue for other zone valves and can be used in residential and light commercial applications, claimed the company. The plastic components of the valve’s actuator are corrosion-proof. The board is sealed, eliminating any chance of the electronic portion of the valve coming in contact with moisture. The valve uses a microcircuit-based logic to control a gear-driven, electronically actuated ball valve to control fluid flow. The flexible configuration of actuator and valve makes for simple, trouble-free installations. Its forged-brass valve body can be installed in any direction, and the one-handed lift-off actuator means that tight space is no longer a factor, said the company. The Zone Sentry is available in two-way normally open or normally closed and three-way diverting, all in ½-, ¾-, and 1-inch versions. Snap-in quick connects make for simple, secure, and fast wiring hookup. A green multifunction LED light shows operation and thermostat status. The manual override button with auto re-engagement allows the ball to be rotated to any position and is marked with a slot to indicate the exact position of the valve.
