Description for Taco ZA024Q4A1

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 cooling applications, primarily designed for use with baseboad, fan coils, radiators, convectors, air handlers, heat pumps and radiant applications.

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 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.

Item was described as a direct replacement for a EN024Q4A2 and it is, but they have made some changes that made installing ALMOST easy. The previous model was locked in place by rotating it 90 degrees on the valve. This model still attaches to the same valve but uses a clip device and it no longer requires rotating to lock in place, a big advantage in tight installations. This unit uses the same electrical connector but the female side has been rotated 180 degrees so you will have to rewire the existing male connector. Pay attention to the diagram supplied with the actuator and you should have no trouble.

I have had to replace two of these controllers in the past 3 years on my home heating system. The valve controls are now an upgrade, looking a bit different but still installs on the same valve. The motors on these new controls are quite a bit quieter when operating.

Comments about QA Actuator For EBV Valves:

I purchased two Taco replacement actuator's from PEX Supply. Was surprised on how fast they were delivered. Ordered on a Thursday and delivered the next day. These are much better than they're older models. The old actuators never closed completely and were noisy when activated. The new model is performing without any issue and is much less noisy. Installation was a breeze and I have no issues with this purchase. Good product and service from PEX. Very happy.

Finally got it right

Comments about QA Actuator For EBV Valves:

Direct replacement for all your failing old generation Taco Zone Valves.

The original concept of this type of zone value was a giant leap in technology. While the concept and design was superior, the construction was not. It appears they got all the bugs out. Time will tell.

The reason this design is superior to the old Honeywell valves is:
1. The actuator is independent of the valve.
2. The valve mechanism is a quality brass and stainless steel Ball Valve.
3. This valve does not continuously consume electricity in the open position, like the old Honeywell valves.
4. Servicing the value requires no tools.

I am currently running 10 Taco Zone Valves on one electronically controlled variable speed circular. This is a significant savings in parts and electricity. Ten valves take up less space then 10 circulators and are easier to diagnose and service. I keep a spare valve and circulator in stock (next to the boiler). In an emergency, if one zone valve fails you can swap it out with no tools.

Comments about QA Actuator For EBV Valves:

I replaced my old zone valves with the newer type TACO only to have the newer valve fail after one heating season....should have kept the old style..

No warranty, but TACO said they are covered for 3 years and are not repaired.

Replaced ten-year-old zone valve actuat

By Toocool

from Eastern Iowa

Verified Buyer

Comments about QA Actuator For EBV Valves:

I replaced two ten-year-old zone valve actuators. The replacements fit right onto the valves. The controls plugged right into the new actuators. The new actuators have an improved latch that works easier than the old ones. If other actuators stop working, replacement is ready to go.

  • QA Actuator For EBV Valves

    Q:

    I need the replacement head for an EE024Q4A1. This is a Type E, 2-way, 24 v, normally open valve.

    I know I need the ZA024Q4A1 for my NC but is the NO different?

    Thanks

      A:

      I'm not sure I understand your question, but the actuators for the NO and NC valves attach the same ways, but the NO and the NC valves open and close on the opposite switch position. Thus one cannot replace the other.

      A:

      Not sure that this motor assembly has its open/close regulated. I believe
      that this valve is neither NO or NC as it requires a 24VAC power signal to
      function inboth open and close. There is no spring that returns this motor
      to a specific position.

      Call Taco at***.****o confirm if you like but ZB024Q4A1 is the newer normally-open actuator for the zone valve, it clicks on to the existing brass valve body with no changes to the piping. This actuator is different from the ZA024Q4A1 that is normally-closed.

    • CUSTOMER CARE

      A:

      This actuator, part ZA024Q4A1, is the correct replacement as long as you have a normally closed valve. The new Zone Sentry actuators work on existing EBV and ESP valves.

      Answered on 3/27/2012 by PexSupply Staff from NY
    • VERIFIED BUYER

      A:

      If your usage is typical you have a normally CLOSED valve that OPENS upon
      actuation, and you need to order the redesigned replacement for the old,
      black, noisy actuator. The new part is SKU: ZA024Q4A1 Taco. It's a
      normally closed acutator that goes right onto the original valve body. IF
      HOWEVER, your use calls for a normally open valve that CLOSES when
      actuated, then you need Taco SKU: ZB024Q4A1.
      Just be sure which one you need.
      Good Luck

      The EBV valves have been replaced by the Zone Sentry valves. The Zone Sentry actuator heads (like this one) work with existing EBV and ESP valve bodies. The new part number for the entire valve is Z075C2-1.
