I'm sure this one will work. http://plumbing.hardwarestore.com/52-30 ... googlebase Or do a search at Aubuchon hardware for ball valve. Dave

Sorry, I misunderstood your quote about the ball valve, I thought you where on about he Velo 350/500 type ball valve, which is slightly different as there is no tap to turn on and off :!:
Don’t know what I was apologising for, but we seemed to have crossed wires here. This is NOT a ball valve but an on/off tap the Velo on that I was referring too works as per following;
A large diameter about 1 inch ball bearing is fitted into a housing held in place by a weak spring that only just holds the seal when oil pump is not working.
The size of the ball bearing is carefully calculated to allow the maximum amount of oil to flow, say the oil pump can pump x amount of gallons per hour then it must be able to flow slightly more than this amount.
The oil pipes to the oil pump are crimped and are air tight or it will fail to retain the oil in the tank. Also before fitting, this feed pipe has to be primed (filled with oil from the top) or it will fail to work.
Those of you who have had one of these will already know that there is a felt oil filter fitted inside a tube in the Velos oil tank.
I suspect that Velo obtained outside help when they designed this method of preventing wet stumping and spent a lot of time, money and effort on it.
