I need to sort out 22mm IMI solder fitting gate valve, in a very awkward location to try to get at, with a weep down its spindle. If managed to slow its weep down, by wrapping the spindle with a bit of waxed twin and tightening the 'gland nut' onto it.
The awkward location means I would rather not disturb the body of the valve. Might I be able to get hold of a suitable replacement insert for it? I appreciate I might need to buy the complete valve.
harry explained on 03/03/2011 :
It is not 'packing style old', it seems it will have an O ring around the stem. Probably 20 to 25 years old, I just tried packing it to reduce the leakage to give me time to get organised to get it sorted.
harry expressed precisely :
Thanks for the reply Harry, I've never needed to examine the working of a gate valve before - at least not one this small :-)
I took the hand wheel off, removed the spindle surround nut and under that was what looked like a brass inner 'lump' around the spindle, from what I could manage to see. Its at the rear of the airing cupboard, behind the pump and other pipe work and side on - so not easy to see very much and why I'm dreading trying to change it.
The spindle nut seemed to be tight against the brass 'lump' rather than tightening up on any packing, which was why I assumed it must use O ring seals.
Do you think the brass 'lump' around the spindle might have packing under it?
