Stuck Lockshield Valve

[nrico2006]

Hi,

Was wondering if anybody had any tips on how to open/close the lockshield valve on a radiator?

I have one valve that did not budge when I attempted to move it with a set of pliers. Is more force required (adjustable spanner?). I was hesitant at putting too much force on the valve in case I damaged it.

Would it be an idea to slightly loosen the gland nut?

Thanks in advance.

I had the same a few times now and in the end had to replace the whole thing as it was well and truly stuck. Try more force with adjustable just steady it with a pair of grips. Be prepared for waterworks.

You could try gently tapping both the body and the spindle and/or squirting a bit of Plus Gas spray around the base of the spindle and let it seep in. Don't apply too much force or you could snap the spindle.

For the price of a new one just replace it !!
