Oventrop Source

Alan (California Radiant) Forbes

I need some Oventrop lockshield radiator valves, 1/2" copper compression x MIP angle pattern. My supplier is out of them. Does anyone have a source they can share?

It may not be an Oventrop. This is the valve I'm looking for.

looks like maybe the runtal valves would work?

Or Hydronic Alternatives

Are you looking for an exact replacement to fit those compression nuts? If so, usually there is a name or logo forged into the body to identify.

If you can start from scratch, and the radiator is BSP or NPT?

If the threads are BSP have a look at Danfos.

Here are some better pictures of the valve. It's an American made Runtal radiator, so NPT.

Looks like the letter OV on one side?
Did you try Oventrop directly at the CT office? Looks like Ferguson carries some Oventrop

Yes, I called them. When I ask for a copper compression inlet, they gave me two part numbers. One is for a valve with a FIP inlet and they other is for compression fittings, but no way to put them together.

Runtal uses Oventrop for all their valves, but they do not sell that compression version - only MNPT x FNPT.

The compression fittings you posted are technically for these Multiflex units in the US market.


Oventrop does not sell the 1/2 NPT x 1/2 Compression valve as a SKU in the USA. If it was purchased in the USA, it was imported by or for another manufacturer. For example Mestek has Oventrop build them exclusive valves for their beacon morris panels (I checked, no compression).

A way you can make that valve from only US sources is to buy 2 valves and that fitting.



But if you have a supplier that can communicate with Oventrop/representative directly, they can probably make it up for you. I can ask on Monday if you still need.

Runtal should have the angle valves in stock. I am sat here with the (probably) exact compression fittings you need but no valve for them. I sent a set of angle valves that was shipped in error back to Runtal about 2 weeks ago, maybe they still have them🤣 !

hot_rod

Are you looking for the exact same replacement valve? Leaving the fittings inn place, swapping the angle valve?
What is wrong with that one?

Sounds like you want 3/4 conical inlet, chose the tailpiece you want, and NPT or BSP outlet.
