Are you the guy who posted here before of your Honeywell hydronic zone valve being sticky?
If so, I worked on one after we exchanged posts, and here"s what I found... a stainless steel stem, about 1/4" OD.
It has 3 grooves and 3 tiny "O" rings.
If that is what you have, penetrating oil isn"t going to work "cuz the 3 "O" rings pretty much fill the bore and oil isn"t going to get in there.
I removed the little snap ring, then wiggled it apart and cleaned the parts up and re-assembled with some silicone lube.
I thought the problem was solved, then it started acting up again.
I replaced the little 24 Volt clock motor and all is well. Typically, those motors either work or they don"t, or get gummy and won"t let the valve close when the power is cut off the motor.
This one worked, didn"t stick, but was apparently weak.
