Taco Z100P2-2 - Zone Sentry Valve - 1" Press, Normally Closed, 2-Way

The Taco Z100P2-2 Zone Sentry valve is a 1" press-connect, 2-way zone valve designed for reliable on-off control in closed-loop hydronic systems. This model features a normally closed configuration and includes Taco’s advanced actuator with microcircuit logic, driving a gear-powered ball valve for quiet, precise operation. Built for energy efficiency and long service life, the Zone Sentry uses just 1.44 watts in hold mode and supports up to 12 valves on a single 40VA transformer.

With a forged brass valve body and internally lubricated polymer gears, the Z100P2-2 combines durability with fast installation. The snap-in wiring and universal body placement make it a go-to solution for baseboard, radiant, and fan coil applications.
