Amperage, or amps, refers to the amount of electricity flowing through the wires.
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.

I installed two of these inside an interior 2 x 4 stud wall between the master bedroom and the living room. These replaced two wonderfully silent Dole valves which are no longer available. One was weeping a bit but I replaced both. The two valves both feed off a Tee coming up from the boiler in the basement, one for the master bedroom and one for the living room. The zone valves are compact and easy to install and seem well made. My only complaint is that when they operate they produce the normal muted, whooshing sound followed by a creaking sound as the valve comes to it's fully open or closed position followed by 3 more creaking sounds as it tries 3 more times to make sure the valve has moved fully. Wish the firmware for these valves could be changed to eliminate the extra "tries" at powering the valves. The extra noise wakes us up sometimes. Too bad these can't be relocated in the basement in my installation.

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.

Easy to use and install

Comments about 3/4" Zone Sentry Valve Normally Closed (Threaded):
I have a water Water Furnace heat pump. I need a good water control valve for flow control. This valve is the only one that works well in this application. Low voltage operation, wide temperature range and any position installation make this valve the best for water flow control in a HVAC system. Taco also give the best product suppoert.
Bottom Line Yes, I would recommend this to a friend

Comments about 3/4" Zone Sentry Zone Valve Normally Closed (Sweat):
I have 3 zone valves of the older generation ones. They kept failing and causing problems. These began working as soon as I installed them. Very pleased.

Comments about 1" Zone Sentry Valve, 3 Way Normally Closed (Threaded):
We used this for hydronic heating to replace the pneumatic system. The ball valves are very well constructed. Do not try to use the manual nylon knob on the motor because it may break but with the use of pliers, the valve can be turned manually. Otherwise, it works with the low voltage applied. A bit noisy because of the rush of water but this also prevents sediment build up in the valve.
Would buy it again

Comments about 1/2" Zone Sentry Valve Normally Closed (Sweat):
I am using these valves on a solar hotwater system. They are easy to install and wiring could not be simpler.

Easy to install
I had a difficult problem to solve, The original Taco Zone valve had quit working after 8 years of constant use and being a sweat connection I was not looking forward to replumbing this copper section. After looking at the pictures on this website I took a chance that the new one although completely different design might have the same brass designed valve as the original. It did! So all I had to do was pop off the old and insert the new. A five minute job. Now my radiant heat is working perfectly again. Thanks Taco and thanks Supply House for your prompt delivery and hassle free service. It actually arrived a couple of days BEFORE they quoted. Yes I will be doing ALL my business with Suppy House in the future, better prices, better service and a much better business model of serving the public than that other company-you know the one with: "no returns" policy.
Best zone valve available

I always use Zone Sentry on new installations and frequently use them to replace old zone valves that are not working.The flow rate is higher because of the ball valve instead of a flapper.Frequently I can use just one transformer where formerly there were two. To keep from breaking the plastic knob that manually changes from open to closed do the following: release the zone valve body from the base, but do not remove it completely. Then turn the body 90 degrees. That will close the zone valve without the danger of breaking the plastic turning knob.
Basically excellent valve
from Goldens Bridge, NY
Replaced a Honeywell zone valve with this unit. This is a much better design, using a ball valve instead of the moveable plastic ball in the Honeywell, BUT the ball is not full port. The actual opening is less than 1/2", though still seems to be less resistance to flow than the Honeywell. Love the LED when the valve is powered up, and the manual control on the top of the valve, which shows where the valve is positioned. Also the way the operator is so easy to remove for service or change-out. Would have given it 5 stars if it was full port.

Just replaced a couple of ancient Eaton Dole Zone valves that I couldn't get replacement heat motors for. I like the ease with which the head can be replaced. The indicator light is a nice feature and the override seems easy enough to turn. So far these are working great.
