Which Mirada pressure relief valve - Zodiac 470

[Brage]

Hi,

First post, new member.

I`ve been reading this forum for years, but never joined. Thanks to everyone posting. Furthermore please excuse my english. If`s any comfort, I can assure you that my Norwegian is superb.

After owning a lot (!) of different inflatable boats I finally got my hands on a (military surplus) Zodiac FC 470. I will never go back.

Two questions;

1, Which Mirada pressure relief valve fits FC 470?

High FlowThreaded - Mirada Research

Is it the B-51343-4 or the B-51343-1 maybe? Please give me an advice.

2, Which plugs fits the same holes as the over pressure relief valves and where can I get them? According to the F470 Field Service Manual I found online, the Zodiac part number is z2936, but I can't find a dealer. Maybe I can use some of the Mirada plugs? Adapters & Plugs | Mirada Research

Thanks, mate. I`ve followed your advice and read the handbook/manual.

The handbook says that Halkey Roberts overpressure valve can be used. They are 4 - 4.9 PSI. The Mirada valve B-51343-1holds 4.0-4.3 PSI, so I guess this is the right Mirada Valve?

The Halkey roberts valve (z3862) sells $40 on ebay (old stock surplus). The Mirada sells for §23 new.

I`m on a budget so I go for the Mirada Valve, if anyone can confirm it is the right one, and that it fits a FC470.

Thanks,

Brage

i guess its down to with the Miranda valve if it fits the hole with no leaks and its within the pressure relief band which it is and to the better blowing off at at max of 4.3 psi rather that 4.9 psi its got to be a winner at 50% of the cost
at the end of the day it just a rubber mushroom yielding to pressure.

cheers

The Mirada valve does not fit in the Halkey Roberts base. The Mirada valves are larger in diameter than the Halkey Valves.

Thanks. The bolt fits the valve.

Looks like Mirada. The Halkey Valves are recessed a little into the tube.

Ok, thanks.

Thanks,

Sorry, gays. I actually took a picture of the fast inflation valve. The bolt in the picture fits the fast inflation set, when the plastic screw on the top of the nut is removed.

On the bright sight however, I now know that the Mirada pressure relief valve fits my boat. These valves have a slightly bigger diameter and is a little bit deeper, than the valve for the fast inflation (and for the valve for keel inflation).

I will post som pictures and take som masseurs so others reading this tread don`t make my mistakes all over again..

Thanks,

Brage
