Taco ZA024Q4A1 Zone Sentry Replacement Actuator Head, NC, 24V #5800022

Taco Zone Sentry� Zone Valves provide on-off, normally open or normally closed control in both open and closed hydronic systems. The valves can be used in a wide variety of heating and non condensing cooling applications, primarily designed for use with baseboad, fan coils, radiators, convectors, air handlers, heat pumps and radiant applications. The Taco Zone Sentry� is the most technologically advanced zone valve ever made. It's also simple to install and operate. The valve can be installed in any direction, in any orientation. We then went a step further, allowing the operator to be mounted to the 2-way valve body in either direction, great for those tight baseboard jobs. Snap-in quick connects on the back of the valve make for a simple, secure and fast wiring hook-up. A green LED light shows full functionality of the valve's operation and thermostat status. Under a no power situation the manual override button located on the top of the valve allows the ball to be rotated up to 90� and is also marked with a slot to indicate the position of the valve
