Zodiac I/C valves seized

[ryza00]

Hello,

I have a zodiac with the I/C valves and the have seized in the inflation position leaving the tubes as basically 1 single compartment.

I cannot budge the valves and have tried partially dismantling them but I am not too sure what to do next, I do not want to apply too much force and end up breaking something.

I have attached a couple of pictures of the valves as they are just now.

Can anyone offer any advice / instruction on how to free the valves off?

The nickel plated brass valves are prone to seizing if they're not greased. First thing to do is to dry them off, then put a rag into the valve. Spray Duck Oil Penetrating Release or Plusgas on the valve and clean off any overspray from the tubes. Do this and leave for a few days, and reapply if necessary.

Check out this earlier thread. http://www.rib.net/forum/f50/servici...ves-46297.html

I've attached a PDF for the 'o' ring, diaphragm, gasket, etc, to order from local Zodiac dealer. Key thing on reassembly is to use a decent marine yellow grease on the metal to metal valve components. Service periodically and you shouldn't have problems in the future. Good luck.
