has anyone gotten this radiator valve apart?

Hi,

Before I struggle more... can these valves be taken apart? I put in a vise, used 24" wrench and it doesn't want to open.

Due to clearance/space issues, I am not able to spin the valve onto the pipe. My plan was to disassemble the valve and thread the body onto the pipe, and then install the stem.

Here is the valve and a picture:

Thank you everyone!
Phillip

    In case it's not clear, I am trying to remove it using this large nut where indicated in the pic

    You may have to put a pipe wrench on the round part. Put a rag around it to minimize scarring it.

    If you look at the "submittal" sheet on supplyhouse, you can see the bonnet is threaded as is the valve body. Should be removable.

    Thanks! I did really scar it already, but that is a good tip for next time!

    Hello, Maybe try quickly heating the bonnet a bit, to expand it, and then see if you can unscrew it. ;)

    Yours, Larry

    I have one of the same valves that rattles from worn parts and want to do the same thing to rebuild it and wondered if it would be a task for heat and or impact gun!!

    Like Gerry said. You can get individual deep sockets from Harbor Freight fairly cheap. Even a long handle breaker bar or cheater on your ratchet. It eliminates rounding off the brass hex.i

    Chinese Krazy glue. Optimus prime couldn't pull that crap apart. Impact wrench if you have one or heat. Or buy an Apollo. They put loctite 246 on but not with a spray gun.

    Do you have enough piping room to add another union on the other side of the valve? Wouldn't have to swing it then.

    I'd be fearful of making the round part egg shaped. Do you really need a valve? How often will you need to shut off this radiator? Could you just use a union instead?

    Or use a gate valve with the stem horizontal?—NBC

    How about a picture of the old set up?

    You need a big vise. Take the tailpiece off and clamp the valve in a vise "end to end" with a couple of pieces of wood on the vise jaws. I would hesitate using a pipe wrench on the round part as you might oval it as @ScottSecor mentioned. A little heat as @Larry Weingarten mentioned is ok.

    Impact wrench and sockets are ok but if you dont't have them put a wrench on the hex, put some pressure on it and give it (the wrench handle) a good rap with a hammer.

    If you don't have a vise, get a pc of pipe with a thread on 1 end about 2-3' long, screw the valve on it hand tight. Rest the pipe on the floor vertically and use it to lever against the wrench
