I am in the process of replacing a gas boiler and the zone valves, and the job is not finished yet...I am a DIY senior. I was skeptical and feared that when received, the valves would not be interchangeable with the old ones, as I did not want to replace the valve bodies, just the guts; got the valves and could not wait so I removed the guts from the old ones and new ones and swapped them; it was a breeze. My hat is off to this manufacturer.The price was right, the shipment arrived in just a few days and the instructions were clear.
Most Liked Negative Review
Not my first choice.
Bought to rebuild existing zone valves. Too many things that can go wrong with motorized zone valves. Thermal zone valves are much more dependable with less moving parts therefore less potential problems.

Comments about 3/4" Sweat Zone Valve (Connection = 18" Leads):
It would be VERY nice if one could just purchase the electrical part of the valve. I had two out of four zone valves fail in our 15 year old residential system. The only thing needed was the valve control and switch.n Alas, we had to order the whole valve, just to get the electrical part. What a waste! Other than that issue, everything was 100% good in this deal. Anyone want to buy two brand new brass valves!
Bottom Line Yes, I would recommend this to a friend

Hot water valve power head
from Klamath Falls, OR
Needed a new power head for an outdated valve. Fit perfectly and was easy to install without draining system. Outstanding service from the people at Pex Supply!!
Solid Construction, Good Value
from Southold, NY
Used these when adding a zone for basement heat. Two weeks in and they're working fine.Recommend taking the motor body and valve assembly off before soldering: There's a sealing O-Ring and the valve seal "ball" is rubber/viton which could EASILY get fried when soldering, even when in the "MAN" position. Besides, it's good practice for when they will need servicing.
Reliable and simple to repair.

Comments about 1/2" Sweat Zone Valve (Connection = 18" Leads):
Can be manually opened to test a heat zone, or for emergency heating if motor fails. I use the aux. switch contacts, in a multi-zone system, to control a single heat pump relay.Use a T-8 torx driver to replace motor. Use a 5/16" box-end wrench to remove or replace the ballseal assembly (suggest removing it to solder the valve body).Rotating ball shaped seal eliminates typical seal failure and reduces "turbulent flow" inside the valve, for quiet operation.Set your T-stat "anticipator" to .23 when using this zone valve. Uses 7.7VA per unit, so be sure your 24-volt X-former has adequate capacity and allow for a safety factor.
Just what I needed at a fair price

Hello, I am a retired plumber and continue to service our home hot water heating system. Your pricing for Honeywell aquastat, zone valves and thermostat was only slightly higher than my local HVAC supply. Since I am no longer able to buy at contractor's discount, I was pleased to find product and pricing comparable to my discount when in business years ago.

Comments about 1" Sweat Zone Valve (Connection = 18" Leads):
This item was very easy to swap parts from with the faulty ones we had on our business' furnace. The cost was very reasonable and the shipping was very quick! We had them in time for the weekend when my husband was home and could replace them. Local retailers I called had to special order them and could take up to 2 weeks to receive.
