Description for Taco ZB024Q4A1

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.

Comments about QA Actuator For EBV Valves - Normally Open:

Worked great! Used it to eliminate the need for a seperate wraparound pump. Tt keeps the water in my indoor propane boiler heated by my outdoor wood boiler while no zone is calling for heat.

      YesTthis is what is so great about them. Just make sure when ordering double check if they are normally open or closed. Never have used a normally open actuator.
