Taco Zone Sentry Zone Valves provide on-off, normally
open or normally closed control in both open and closed hot or chilled water systems. The valves can be used in a wide variety of heating and cooling applications, primarily designed for use with fan coils, radiators, convectors, air handlers, heat pumps and radiant applications.
The 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. Taco then went a step further, allowing the operator to be mounted to the valve body in either direction (see Figure A of the manual in the "Manuals" tab), 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.

Simple and elegant in both design and function; compact too. I bought a pair of these to replace several small circulators, combining these zones onto a common variable-speed circulator (Grundfos Alpha).The valve head includes a capacitor which charges in about half a minute and discharges only when activated. Thus, a single 40Va transformer will power more of these than most houses have zones. I prefer the threaded pattern to avoid overheating issues while soldering, as careful as I am, so I cannot speak for the solder version. Can be used stand-alone or with a zone valve controller, so adding another zone should never be a problem, if you have used all of your zone controller slots.

Overall the unit works as it should but the cheap plastic override was a surprise. I pressed in and turned then it twisted off. Obviously I thought the value was turning when in fact it wasn't. The valve is brass why cheap out on small part like this? I'm not sure I'd recommend this brand of zone valve until I've tried others and used this one longer. If it goes past 10 years w/o leaking then I can over look the cheap manual override and bump it to 4 stars since I can take the controller off and turn it with a pliers.

Bypass a little weak
from Mtn.View Wyoming
Comments about 1/2" Zone Sentry Valve (Sweat):
The change from a plug type valve to a ball valve is great. The new latch/ removal system is very good. The only weakness is the plastic bypass.As the valve ages the plastic will probably become more brittle over time.Taco should make the bypass button from metal.
Bottom Line Yes, I would recommend this to a friend

Comments about 3/4" Zone Sentry Zone Valve (Sweat):
It's a valve.
The in stock selection and prompt shipping is great. My plumber can't believe how quick I can order and receive what he needs and he cannot match the prices locally. Thanks

from Brooklyn, NY
Quick and professional service. Thanks.
Hope the new model is more reliable
from Alberta, Canada
Had the old version of this unit it was very noisy and only lasted about 3 years before it failed. The new model is quiet hopefully more dependable. I can't blame Pex Supply for these issues as they are not the manufacturer. Pex Supply was prompt in getting the order to me in a timely fashion.
from Schenectady, ny
Works like a charm. Valve control can be serviced or replaced with out removing the valve.
easy install, great functionality. design makes servicing very easy.
