Taco ZA024Q4A2 Actuator Head Zone Sentry Valves 24 VAC,
,

Taco ZA024Q4A2

18" wire lead connection

A snap on actuator allows for fast installation and easy replacement with a convenient in-line push button.

A gear ratio of 21:1 in the actuator increases torque for high close-off pressure and increases closing time to reduce water hammer.

Compact design provides quick and easy installation, the Z-one valve fits perfectly inside baseboards and fan coils. Available with choice of NPT, sweat and press fittings for ease of installation and maintenance.

Hermetically sealed end switch in 24V actuators requires no minimum current load allowing multiple end switches connected in parallel to zoning panel.

Suitable for all types of systems - made with materials compatible with chilled or hot water up to 240°F, 15 psi steam, and open or closed systems.

Low power consumption allows up to five valves per 40 VA transformer.

Taco Zone Sentry zone valve enhances the overall performance of any zone valve system. The unique patented technology in the Zone Sentry utilizes a microcircuit based logic to control a gear driven electronic actuator which drives a ball valve based body design. All this adds up to a zone valve that leads the industry in energy efficiency, flow capacity (Cv), shutoff pressure rating, ease of installation, diagnostic capability and the number of valves (12) that can be use on a standard 40 VA transformer.
