Anyone recognize this rad valve?

[bungditin]

Need to replace all the rads in a customers house but i have an feeling it's a one pipe system because of the valves.They are swedish and are around 30 years old,help appreciated.the valves are in the middle at the bottom of the rads.

Nah ,it's a 2 pipe ,you'll confirm this when you get floorboards up

never seen these being replaced... reckon it its new rads time

 

[bungditin]

Yes the rads are being replaced and with valves at either end.

 

[gavinda]

then it doesnt matter about what vakves they are.

From what little i know about the valves is that the rads form part of the system,when the rad is turned off the flow continues through the chrome part of the valve,if this is the case if i fit a rad as normal when the wheelhead valve is turned off the rest of the rads in the house shut off so i may need to fit a length of copper between the flow and return (bypass) to continue the flow around the system.

never seen these valves on a 2 pipe setup. these are at least 25 years old and normally fitted on 1 pipe systems

Just need to find out if when the rad is off the flow contineus through the valve,looks like stripping the valve to find out,thanks.

 

[gavinda]

but as we cant see his system from here and crystal balls are offline, it would be best he lifet the floor to investigate. which he'd need to do to put in the 1 pipe bypasss anyway.

 

[bungditin]

I'd put the bypass inbetween the tails going into the rad above the boards.

 

[gavinda]

but for the sake of lifting a board you might save yourself some hassle and copper and not hang the rads so hig up the wall and add an unecessary bypass to every rad and make the system less efective....

but hey you asked a question and dont like the answers

Are you sure that you have enough experience to be replacing all the radiators?

asking for advice in a customers house from a diy website says it all

council/association type of valve, one pipe system, valve has built in by-pass. Time for a re-pipe
