Dinghy Valve repair

I have a soft bottom dinghy I would like to repair.
It is a Boat US made by Severn
The valves are all shot. They do not hold air at all.
There are three valves all the same one for each tube and one for the keel.
There is forth valve a different style valve the Bravo for the inflatable floor.

The easiest would be to just replace the valves bodies but I can not find them.
I hear it may be possible to cut out the old valve and use a doubler and a new valve. What would you recommend.

How do I find out if this is a pvc or Hypolon boat?
The first to pictures are of the three boat valves the next two are of the one floor valve.

Also it would be nice to have all four valves the same.

Re: Dinghy Valve repair

These valves look similar to the West Marine brand (made in Croatia) inflatables / valves used/sold in the late 90s. Depending on the brand of the inflatable, check with West Marine 'Special ordering' department for these valves. Good luck.

I edited the post with the name of the dinghy.

Re: Dinghy Valve repair

I called nrsweb.com and sent them my pictures.
Their tech support guy said that the valves I have look similar to but are apparently not exactly the same as standard valves. He used the term potential knockoffs.
He recommended replacement C7 valves:
4 valves #1482 @ 21.95 = 88.00
4 Donut patches to fix the hole after I get the old backer ring out #1482.9 @ 3.50 = 14.00
One valve wrench #1482.1: 8.00
Pint of special glue works on Hypolon or vinyl #1903: 29.95
On valve adapter #14821: 4.45

Total about $150.
Not sure if the boat is worth it.

Apparently the valves can be easily replaced if you can find the exact match.
You unscrew the out part and leave the inside ring so you can screw in the new inner part.

If you have to replace the whole valve you have to get the inner part out which is bigger than the hole so you have to make some kind of cut and then patch the boat with a donut shaped patch.

So like most things it is possible to repair but the cost may exceed the value of the boat.

Re: Dinghy Valve repair

NRS is a great place. If you do change out the valves put in the C-7 Leafields,

What you have looks to be Halkey-Roberts, not bad, but I have seen failure with that yellow button getting brittle and rendering the valve useless. Is there maybe sand in them.

Oh mind you, I am coming from the white water rafting world.

Re: Dinghy Valve repair

I'm afraid, if the valves are shot, there must be more waiting in line. Inflatables are not lifetime items, unfortunately. I would ask how old it was, but longevity depends a great deal on use and exposure. It would only be relevant if it was fairly new and these valves were defective.

I would think about a new (or used) replacement and put the money for this and the next few repairs to better use.

Re: Dinghy Valve repair

In the hope my experience may help someone else I will confess what the problem was.
I got the owner of the boat out to the dinghy after all summer and she said she remembered that there was something about twisting something but she couldn't remember what.
It got me to thinking that the chances of all 4 valves going at once vs the chances I didn't know something.

Here is what we found out:
In the center of each valve is a pin with a spring attached to it.
If you press in the pin the valve leaks air, this is what I expected.

What I didn't expect is that if you press the pin in and turn to the left the pin pops out more and the spring expands and it acts as a valve.
If you press the pin in and turn to the right the the pin stays pressed in and the spring stays compressed and it leaks air with out having to hold the pin it.
This makes it easy to roll-up.

Now that I know it is obvious but since I had not seen it before I had the pin set the wrong way when trying to inflate.

I'm assuming that all valves work this way and it is so obvious it is never mentioned.

So at least now it is mentioned.
