Erie AG13A02A Actuator 24V 18" Leads, 1" x 1" x 1"

I always keep some of these around for replacing failed 20-year-old units. I have 2 boilers and 4 zone valves to deal with. Simple lever attachment to the existing zone valve, and 4 wires to connect. The hardest part is diagnosing the problem to begin with. In this case the old actuator worked, but the limit switch to start the boiler was very intermittent, so the boiler would fail to start after a few times. On my boiler it gets about 3 tries, and then the boiler controls lock-out.

One of five met the end of the road, so to speak. Replacement took me about five minutes (even remembered to turn the boiler power off first). Just pay attention to rotating it slightly when installing it over the shaft sticking up from the inline portion. Google, and a son being a technician in the field allowed me to be prepared. This unit has performed flawlessly.

If you have these pop top zone valves in your hydronic heating system consider yourself lucky because these are a breeze to change. I always keep 1 on the shelf for peace of mind that I won't be left without heat to a zone.

I am not a plumber, or an electrician, just a DIY home owner. This was easy to replace and it saved me $250 from the oil company doing it for me.

Almost like clockwork, this model fails at about the 12 month mark over the last 3 years ! I would have given it a 1 star rating except the company so far has stood behind its warranty and have replaced the failed units free of charge albeit the company that ships the part is slow in getting the part out. And let’s not forget the cost to have it replaced each time it fails.

This zone valve head directly replaced a defective one of the same model number on my hydronic boiler heating system. The swap took about a minute. No need to worry about which wires go where, because it's pretty much a "switch" on the black wires and red ones. One thing in the manual that I did not see anywhere else was that you need to lock the unit into the "Open" slot before installing it. I think that just lines up the flat part of the actual brass valve part behind the motor head. When you restore power to the system and this thing sees the call for heat, it will automatically move the lever into the regular position.All in all, great value for a critical component of my system.

My husband had this replaced on our 1970s boiler in about 5 minutes. Would have been done sooner but he didn't realize you needed to open the valve before installing.

Didn't need. Returned.
