Erie Zone Valves

I`ve used them, no probs/issues so far.

I prefer them over the honeywell equivalent

gost flow

have heard of gost flow problems with them but that may have been corrected. I use the callefie zone valve. Its the same thing.I have hundreds in the field no failures yet.

erie zone valve

my heating contractor replaced my Taco zone valves w/Erie pop/top valves and its been a horror show since. i have a zone which has nothing but what i call "water hammer" when
thermo cuts out. i have had contactor check for air entrapment and just about everything else to no avail. having all 4 valves pulled before pipes burst.

Taco 570 series has a generous three year warranty on the replacable actuator, and a whopping 5 years on the replacable valve seat assembly. How's that for product confidence? For your reference I attached the catalog data, or visist www.taco-hvac.com for information on any taco products.

hammer

are they orientated correctly--should be an arrow on the body showing flow direction. Supply or return side, out of curiousity?

I agree with Joe.

I really like the "slow acting" properties of the Taco zone valves personally.

The proof lies in the piping with zone valves. The dough spent on a pressure differential by-pass, is worth whatever it costs. Both fast and slow acting valves will cause an uproar if the pump is going full tilt boogie...and the valves shut down suddenly.

Set properly, the differential by-pass has proved itself time, and time again.

I like the electricity savings with zone valves also. 24V VS. a 120 pump...just makes sense. With the zone valve controls available now...the wiring becomes a moot point. The old style wiring took some thought and calculating...where anyones ZVC control takes the guesswork out of the equation.(the ability to READ a manual still comes into question sometimes...but I digress)

I think that zone valves will become the norm in the near future, with the price of fuel and electricity going nowhere but up. I applaud companies like Taco for taking the initiative to simplify the wiring so much...and truly believe that the PDB (PBD, BPD whichever you prefer) will become standard practice as the electric rates rise. JMHO. Chris

no idea how many hundreds out there.

not a single failure yet.

water hammer is an issue for some systems, perhaps, but if so it's not because of the zone valve, it's because of improper system setup. I say that as a person who is experiencing it on a job that is not using these zone valves

plastic gears

I have had promblems with them a few years ago,it seems a large plumbing and hvac company had done alot of custom homes that where oil fired excepet they do not service oil fired boiler so i ended up there .The promblem that they contained plastic gears and it seemed after about 2 years the valves would open but the gear would slip and the valve would not make the mirco switch this had nothing to do with the motor because i had replaced them also but with in a few days the promblem would re appear .I removed them put in honeywell and have never got a call back asscioted with them peace and good lucl clammy

Try the Caleffi

I like the features they offer. It is a motorized valve, but slow opening. Easier to assemble and "pop" than any of the other brands.

I recently installed an EK1 with Erie valves on the supply and notice a bang when the zone stops calling. My guess is the valve closes too fast. They are installed correctly.

I specifically requested Honeywell and NOT Erie, but obviously someone knows better than me!

Failing Actuators

I have a commercial building with Eries installed in 1999. We are experiencing lots of actuator failures...like you said plastic gears. They either stick open or closed. They do have a kit to replace...so we don't have to do the whole valve. Out of 100 valves we have replaced about 25 actuators.
