Seacock Question

[Deleted User YDKXO]

It's extremely hard to believe that whoever produces these seacocks (which obviously isn't Ferretti) wouldn't supply them directly.
Now, finding who such producer is, that's a different matter. Dontcha have any pics?

No, obviously, it isn't Ferretti who produces these things but probably an exclusive supplier. I only have a lousy pic of the seacocks which doesn't show much but here it is anyway

Yep, what I meant is that if you can find this supplier and get in contact with it directly, very often he's happy sell you his products at maybe twice the price he gets from his "exclusive" client. Which could well be half of what Ferretti would ask you...

Anyhow, sorry, but I can't recognise those seacocks.
Btw, they're indeed weird, 'cause the handle seems placed on top of the "T".
And if so, I can't even understand how they work...!
The typical T ball valve is as posted by DM1, with the handle on the side of the T.
And I'm pretty sure to have seen a Ferretti of similar size as yours with valves like those ones.
TBH, I'm not sure if they were the original equipment or not, but if not it means that also any standard T valve can do the job.

Yes sort of like that. Whats it made of and who represents Bola in UK?

They're pretty much the same as the seacocks fitted to my previous Ferretti 46 here

so I guess the ones on the 53 are original fitment. I understand what you are saying ref exclusive suppliers but normally exclusive suppliers don't sell outside for fear of upsetting their customer.

Blimey, I can't get my head round the way these valves work.
I suppose that the third outlet of the "T" is not visible, because it's below, attached to the hull.
And the other two visible outlets are for the engine cooling raw circuit and for the bilge pick-up, to use the engine raw water pump as a bilge pump.
If that is correct, which are the engine pipes, those going sideways or downward in the pic?
And what are the possible positions of the handle?
Just curious.

Yup, you cant see the inlet to the seacock because as you say, it's below attached to the hull. On both boats the engine pipes come out of the top of the seacock and, as you can see, the first section of each pipe is a 90 deg solid bend. On the 53, for some reason, the engine pipes face aft and then curl around 180 deg forward to the engines; you can just see the flexible pipes in the pic.
The bilge water pick ups from the seacocks go off to the side horizontally. The levers are positioned both vertically upwards for opening the cock to the engine pipes. For bilge water pumping, the levers would be horizontal and for closing the seacock, the levers would point vertically downwards
I have never seen the exact mechanism inside but I guess it's a ball with a hole bored through it and another hole 90 deg to the side

Mike, DELETE! DELETE! DELETE! Talk about knowing where the bodies are buried. One of their fingers is sticking through the hole on the left of your picture.

Precisely.
That's how valves like the one posted by Divemaster1 are built.
What I can't understand in yours, if you think about it, is the rotation axis.
With the handle placed on top of the T, the rotation axis can only be along the vertical segment of the T, so to speak (the sideways outlet, in your pic).
Which means that there's no way to open/close the sideways outlet for bilge water pumping, because the side of the ball pointing to it remains always the same, it can only rotate but not shift.
There must be some other trick in the way they're built.
Anyway, the space should be enough also for standard T valves like the one posted by DM1, which surely cost much less.
You would just have the handle on the side of the T rather than on top of it.

My first point of call would be Hydrasun as they have a local branch, and deal with Marine and Offshore...
