Description for Taco Z075C2-1

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

By WyoGrizzly

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.

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.

  • 3/4" Zone Sentry Zone Valve (Sweat)

    Q:

    My new baseboard hydronic heating system has 1/2" Supply and Return lines (increased through the 3/4" Slant Fin Baseboard then reduced). What size Taco Sentry Zone valve should I purchase 1/2" or 3/4"? I was thinking 3/4" to get more flow/pressure.

      A:

      Hi,
      It doesn't sound like your system designer knows what he is doing. 1/2 inch copper is probably inadequate for heat system distribution. Putting in 3/4 inch zone valve(s) will not make any real difference.
      Good luck!

      A:

      If there is not to much price difference I would go with the 3/4" but I expect the pressure drop on the 1/2" would be very minimal give the low flow rate through each rad.

      A:

      Your statement " I was thinking 3/4" to get more flow/pressure." IMO the
      flow/volume and pressure is controlled already by the 1/2" supply and
      return lines. Changing the size of the Taco valve will have little
      impact. I would just match the existing line size (1/2") and avoid the
      additional sweat joints

      A:

      1/2" are fine. Your system will be limited by the 1/2" tube so that you
      don't have velocity noise. Up sizing just the valves won't gain ya much.

      Answered on 7/9/2014 by Anonymous
    • VERIFIED BUYER

      A:

      Since the supply and return line is 1/2" there is no advantage to buying
      3/4" valves. Besides the fluid must remain in the finned baseboard unit for
      effective heat transfer so a slow circulation may not be an issue.

      3/4 will have less pressure drop then the 1/2" will. Cost difference is
      minimal.

      Answered on 7/9/2014 by Anonymous
    • VERIFIED BUYER

      A:

      I am using a 3/4 valve which has a nearly straight through path, so the pressure drop introduced by the valve is minimal. Assuming the construction of the 1/2 valve is similar, it would perform as well as the 3/4 in your application. So you would not likely get more flow with the 3/4 valve.

      The 5101G can be used in open systems, while this zone sentry should not. V075C2G2ZA024Q4A1 would be the zone sentry equivalent.

  • 3/4" Zone Sentry Zone Valve (Sweat)

    Q:

    Should I step up a size, need to install cutoff valve on existing 3/4" copper mono loop system and am worried that the opening in the ball valve is only about 3/8"

    Will this restrict the flow too much and if so would it make sense to move up to the 1" or 1 1/4" valve so as not to restrict the flow?

    Thanks

    • A:

      This valve has one of the highest CV ratings in the market. CV= the amount of 60 degree water in gal/min. flowing through a fully open valve at 1 psi. It is the least resistant to flow than most other zone valves. The flow thru one part of a pipe is the same as the flow thru any other part of the pipe. What happens is the water speed up passing thru the valve. The 3/4" and 1" valve are the same except for the size of the copper pipe that can be soldered to it. You know, the max flow thru 3/4" pipe is about 4 gal/min. (about 3'/sec.). If you need that flow you can always use a bigger pump.

      Answered on 6/16/2012 by Homer from Nevada
    • CUSTOMER CARE

      A:

      The 3/4" valve is equivalent to about 8.4" of pipe when calculating flow, while the 1" valve equals 47.4". Since the bore sizes on these valves are about the same, stepping up a size probably wouldn't be worth it.

      This valve is only recommended for closed-loop systems. It will rust in an open system. You may want to take a look at Taco's geothermal zone valves, which are designed for use in open systems.

      The ESP valves are obsolete, having been replaced first by Taco's EBV valves and now by the Zone Sentry. The Zone Sentry head (part ZA024Q4A1) works with both the ESP and EBV valve bodies.
