Maintenance valves Blakes
During this time my boat is on the ground, and I am personally of small maintenance jobs. Today I cleaned and polished the inner cone of the two valves Blakes. I wanted to share the results with you.

So when you assemble these valves - which type grease should be used? We have this valve service in near future.

I have tried different brands of grease and my conclusion is that, although any marine grade grease will fit, the original product suggested by the manufacturer is indeed the best. I acknowledge that not everybody agrees especially because of its higher cost.

Dear Giuseppe,

Daniel is absolutely right, there is a grease which you can buy here: http://www.force4.co.uk/blakes-lavac-taylors-seacock-grease.html#.VOJY6MZrSbk

It is not really expensive (but must add shipping to Italy) and perfect for the Blake seacocks

Fair winds!

Nice job! This year i must to replace the Blakes seacocks, on my 411. Anybody suggest me some reliable alternative to Blakes? The bronze, is always the best? Where can i buy them it in Italy (or on-line) at the best price?
Thank you all!

I hope that I will not be condemned for apostasy.
After a couple of handles broken, poor threads of the nuts and other unconvenients ( also due to poor maintenance), I have changed all the sea cocks. I have these:

Pardoning is difficult but always possible and desirable.
Apostasy? In this case, just an obvious fact!!!

Dear Carlo
Bronze is recommended for the engine room where a fire may melt a plastic valve.
Suggest you check if Maestrini has a suitable model.
There are several manufacturers in the USA - Perko, Groco, Buck Algonquin, Apollo
Kind regards
Lars

the topic of fire resistance of metal seacocks has been discussed in this thread, too:
http://www.classicswan.org/forum/post_thread.php?thread=874
I wonder, too, in how many cases are there throughhulls in an engine room. And, too, what is the resistance to melting for the plastics and rubber in a modern engine. In my boat I have bronze connections in a distribution box the area of the raw water filter and other connections to the generator and the dissalator.
Apart from this,I have plenty of piping in plastic or rubber, which should be, too, specified. And insulated wires,too. I do not know their resistance to melting.
I would like to add, for the italian and french market, mainly, that there is a french production, another 'plastic' producer, RANDEX, of reinforced seacocks. The distributor in Italy is www.vallescrivia.it and the responsible is Mr Zerbinati, who has a strong reputation in Italy, with regards to maintenance and surveys.
Fair winds, it is springtime now!

After 40 years we still have the original Blake bronze sea valves but for the toilet which corroded badly three years ago.
Using Blake grease allows us to keep the boat in the water for two years without problem.
So why change???
Also one needs to be very careful about the type of fitting used on the through hull part itself.
What are you going to use? If its metal watch for brass!!
To me Blake sea cocks are the best by far, and can still be found on the net.
The only problem: they need Blake grease!!
All the best.
