On many of the valves not frequently used we removed the handwheels to prevent accidental operation. As to the gatevalves in the venting systems for MBT/fuelreservetanks 2 and 4, the gatevalves were only operated when changing the systems from ballast and fuel configuration and vice versa. I guess the standard would be to remove the wheels. A wheel wrench is a tool very often used by the crew for many type of valves. If you study the "sliced" XIC in US you`ll find many gatevalves in the casing, most of them tilted to accommodate the high valvecasing,  a drawback of the gate valves. The images are from a IXC but I guess the same valves are used for the VIIC as well. You may see quite a few of the valves have no wheels fitted and are even operated by bevel gears and rods, I guess however on a VIIC they were mostly locally operated..

Hi Simon,


Great info...  I have attached a photo that shows the FBT 4 and FBT 2 vent holes in the saddle tanks.


I have marked with red dots on your drawing where I believe the FBT 2 residual gate valves are located under the wooden deck hatches. Do you think this is correct? Also, is there room to have hand-wheels attached to these gate valves under the deck, or were the hand-wheels always removed for this set as well? That photo I had of a crewman getting out in bad weather with a hand wrench (Claw) tool makes me believe the hand-wheel was once a possibility...

Hi Don,

I have not research the FBT 2 residual gate valves http://www.uboatarchive.net/U-570/U-570Plate16.htm valves b1 or d1 so I not sure. Since I am working on the saddle tanks I was soon start working on the piping that are found around them.

Don, the small hole in the deck is a access hole for a locking handle for this hatch (see below). I not sure how the locking system works, you either lift or push down on the handle.

Hi Don. Yes we are back in the civilisation, only to discover we forgot a couple of important items which shall be picked up by our grandson this week. Although we have had our first frosty nights, no snow as yet don`t miss it in my age. It take a few days to get back to the daily life in the city, but we are almost there.

Hi Dougie,

We were wondering about the colour of the actual liferaft itself, not the container/hatch.  :)
