V32 Proton on 300bar cylinders

[Slks-scuba]

Hi,

I have a Mares V32 proton ice and proton metal reg sets and both are run on 300bar cylinders, But it seems I am having to have the first stage valve seat replaced way very often and neither set makes an anual service.

One service center has said there is an issue with th v32 when used at 300bar, due to the way the valve is constructed and the materials used. Now i am a little concerened as i have two v32 stages and both have had the same failure far to often that leads to second stage overpressure leaks.
I even press te purge when opening the tank to try and limit the initial pressur surge on the valve seat.

Has anyone seen similar

Cheers

I suggest you have your service center replace the V32 proton seats with our new trimaterial poppet and seat. We have found the new system to be extremely reliable and durable in all conditions! I am quite certain once you upgrade your issues will become obsolete.

Best,

I have been using the new tri-material HP poppets in a number of different regs. In fact, I have a few from one of the earliest production runs. Their performance has been exceptional. I have two that regularly see pressures in excess of 230bar, and their intermediate pressure remains rock solid after many hours of use. I am keeping careful records to determine how long they will last before servicing is needed.
