Titanium Seacocks are Here

The Titanium Life Seacock is a premium marine valve developed after four years of dedicated research and development to meet the highest standards of quality and performance. This Patent Pending valve design was crafted from Titanium Type 4, this valve is specifically engineered to withstand the harshest marine environments, offering exceptional corrosion resistance and durability that surpass traditional materials.

Key Features:

Material Excellence: Made from premium Titanium Type 4, known for its outstanding strength-to-weight ratio and superior resistance to saltwater corrosion.

Size Range: Available in sizes from 1/2" to 8", filling a unique market gap with titanium construction across a broad range.

Robust Handle Design: Features a solid 3/4" key way to a 1/2"rod handle , providing maximum torque for smooth operation and eliminating common issues like galling and handle failure.

Thick Baseplate: Ideal for thin hull installations, ensuring a secure and durable fit.

Three-Piece Construction: Allows easy disassembly for cleaning and repairs without removing the base, simplifying maintenance.

Reliable Sealing: Utilizes a simple yet effective PTFE gasket seal and ball for leak-free operation.

Safety and Longevity: Requires no bonding unless mixed metals are present, preventing galvanic corrosion and enhancing safety.

Durability: Constructed with ample titanium material to protect against damage during handling and installation.

The Titanium Life Seacock represents the pinnacle of marine valve technology, designed for mariners who demand reliability, durability, and superior performance in the most challenging conditions. Experience peace of mind and unmatched quality with this state-of-the-art valve.

Are these fully titanium including the ball and hardware?

Are they designed to work with an accompanying titanium thru hull?

Do you source or manufacture pipe fittings or king nipples in titanium?

Do you have any long term use on aluminum hulls, or reccomendations for installation on an aluminum hull?



Had 2x friends loose thru hulls this year, one a maralon that catastrophicly failed from what we think was vibration and another from an aluminum extrusion that corroded from electrolysis and failed. Think they would be willing to consider titanium at just about any price to avoid the fun they had dewatering in a panic.

 

And there is the 64 hundred dollar question. The telling quote in the OP post is " Requires no bonding unless mixed metals are present, preventing galvanic corrosion and enhancing safety."

I could see this working on a composite hull (except CF!) if everything else (thru hull, bolts, nipple to hoses, etc) were also titanium. A metal hull that isn't titanium? <shudder!>

 

Perhaps its just me but I am puzzled by the notion of using ultra light components below the waterline.There may be some kind of very small notional advantage in a high speed boat,or is it just bragging rights?The hefty caps on the ends of the barrel plus the very stout nuts do run counter to the lightweight part in any case.

 

I think you missed the whole reason of these fittings. It is not the weight but the long term (almost infinite) corrosion resistance. Unfortunately, titanium (especially medical grade Type 4, i.e. almost pure) is very cathodic and will eat up almost everything except carbon fibre electrically attached to it.

 

I didn't miss it,but I do wonder where,outside owners of those fabled Russian titanium hulled submarines,such a piece of hardware has any application.The fittings seem massively oversize for installations that won't see more than one bar of pressure in a surface vessel.

 

"Carbon Fiber you say, hmmmm, interesting."
For the man who has everything including the CF yacht.

 

Again, for piping, the material is selected for corrosion resistance not strength. A large number of warships now use titanium for piping in the fire main and flushing systems. There are relatively low pressure systems filled with seawater that can sit quiescent for months but reperesent a major maintainence cost over the life of the ship when made of steel (and NO composite fire mains on a warship). Making the systems out of titanium is a cost and operational advantage over the 30-50 year life of the ship.

Edit: Sorry I missed the thrust of your post. You need that much material for a well designed ball valve. Unlike a plastic one where the enclosure is glued, you need space to put the bolts.

 

Notice where titanium and graphite are on the Galvanic Chart.

 

Titanium hulled yachts do exist, even if you can count them on one hand.

From a corrosion perspective in practice you are always going to have to install a zinc anode in the circuit since avoiding mixed metals is very hard. Fortunately this is normal for engine cooling circuits but it would have to be replicated elsewhere. If you have a salt water faucet you either install a anode in the line or be very sure everything else is plastic or titanium. If I were to sell titanium valves I would design them to include a pencil zinc housing and mandate a frequent regular inspection regime for the anode.

Every material has its drawbacks one must accept and live with. Titanium is like balsa core, wonderful if done and maintained correctly and a nightmare if not.

 

Sorry about not posting a response sooner, I was traveling. Hopefully this will answer the questions:
1. Everything inside the valve is grade 4 titanium with the exception of the PTFE gaskets. The ball has been hardened.
2. The body is large since it is a 3-piece valve. I am pretty sure that most all that is currently offered are two piece, and two piece non-serviceable.
3. It was made a a 3-piece to make it life time. This allows a complete breakdown and cleaning. Note that the valve should still be open and closed on a regular basis just like any other since sea growth is non stop.
4. Yes, we do have the fittings in production. They are type 2 titanium. I would this the best case scenario would be to barb to a short hose piece then connect into the raw water system to save money.
5. Yes, they are made to work with NPS through hulls. I believe Titan makes these.
6. They are not made to save weight. They are just as heavy as a good bronze valve. This is due to the 3-piece construction.

I have included some picks to show the ball and the gaskets as well as the base, which would be left attached to the hull while cleaning.
