Taco Inc.: Radiant, Heat Pump Zone Valve
December 20, 2010
The Zone Sentry™ zone valve’s patented technology uses a microcircuit-based logic to control a gear-driven electronically actuated ball valve to control fluid flow. The advanced design uses 93 percent less energy than common zone valves while also delivering greater flow capacity, shutoff pressure rating, ease of installation and diagnostics, and the number of valves (12) that can be used on a standard 40-VA transformer, claims the company. Ideal for use with a wide variety of heating and cooling applications, Zone Sentry valves were designed primarily for baseboard, fan coil, radiator, convector, heat pump, and radiant applications, says the manufacturer. The valves are available in ½-, ¾-, and 1-inch sizes and draw 1.44 W. They can be used in both residential and light commercial applications. The forged-brass valve body can be installed in any direction or orientation and the one handed lift-off actuator means that tight space is not a factor. Snap-in quick connects on the back of the valve make for simple, secure, and fast wiring hookup. A green multifunction LED light shows the valve’s operation and thermostat status. The valve’s 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.
