Ball Valve Zone Valve
Application:
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.
Ease of Installation / Operation:
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.
