DISA valve gasket damage?

The Nightman · 03-12-2018, 08:58 PM

I purchased a used 3IM and noticed that the gasket on the small DISA valve (PN 11617560538) was damaged in two sections:

Here is how a new DISA valve looks for comparison:

And where it goes:

Is this valve still usable or should it be replaced? Other than the damage pictured above, the valves appear to be in good condition.

Update:

For posterity, I was able to repair the gasket using Krazy Glue and it installed fine. However, the valve's servo motor is faulty and it triggered code 2AAC. There was a significant amount of oil on and inside this valve so I suspect the oil damaged both the gasket and motor.

Never seen damage on that side of the valve. Usually the internal seal breaks away. I can't comment if that is a deal breaker or not. When I pulled my 3IM apart my large DISA valve looked like this:

That'd be a no Bueno for me...

They are a super snug fit. I had to really put some pressure on them to seat them. Next time i will probably use some rubber grease inside the manifold but i thought the film of oil inside would have been slick enough.

Even when i removed both my existing valves and both the valves out of the donor manifold, I had to use a prybar. I reckon the seal had bonded to the manifold and tore a bit on the way out.
