Valve storage
Hi
My valve collection currently resides in cardboard boxes in the garage. I am thinking of rationalising and transferring them to plastic boxes with lids. What are peoples' views on this. The only drawback I can think of is that if there is any moisture on the valves it will be trapped. thanks Jon |

Re: Valve storage
Mine are in the original, or replacement card boxes, and then in plastic or cardboard boxes.
These stored in the loft, garage, shed, workshop, and even a few in the bedroom, apart from the valves that are in display cases in the lounge. I've never had any problem with dampness, but most are in heated areas, and all boxes are opened frequently. I suspect that the best answer is to keep them all in a heated area (which in my case would mean getting a larger house) or not to keep so many! |

Re: Valve storage
I wouldn't bother with special measures, worst case with moisture, dirty pins (sand them clean) worst case moving them around, a box of broken glass!

Re: Valve storage
I think being stored where there is a large variation in temperature can increase the probability of them cracking but generally they are pretty tough. Severe corrosion around the pins can lead to metal/glass failure but I have boxes of them in the loft of my garage loose in cardboard boxes and they have been there for years.

Re: Valve storage
I keep mine in a dry warm environment, I had a few go down to air due to being stored in a damp shed. I am sure the sub zero winter temperatures did not help either, also I have seen 40 degrees in the summer months!
Most B9A types had cracked around the pins. Mark |

Re: Valve storage
I inherited a quantity of valves that had been stored in a cellar and although it appeared to be dry many of the boxes fell apart when touched. So I have about 50 new valves that are minus the outer box but have, usually, the inner wrapper where there was one. If it was just a box then I only have the valve.
It looks as though they just rotted away - they just turned to dust when touched. |

Re: Valve storage
I keep mine in a cupboard in the workshop, the room temperature rarely drops to 10 degrees, the dehumidifier goes on during the winter months.

Re: Valve storage
Be careful of storing stuff in attics - though they should be dry, they can suffer massive temperature-excursions.
A friend of mine put his home network Ethernet switch and router in the attic - the logic being that it was both out of the way and high up so would give good WiFi coverage. It kept rebooting - on investigation the bulk-air temperature in the attic was hitting 60 Centigrade on summer afternoons and the switch's exhaust-fan air was about 75 Centigrade. Not good for the health of electrical components! |

Re: Valve storage
Hi all
Many thanks for your replies. Looks like I will be OK transferring my valves to plastic boxes but need to beware of temperature fluctuations. Regards Jon |
