Forge DV007 Recirculating Dump Valve - 7 years on

[Rusty]

Just taken my Forge DV007 apart after running it since around 2007 with no maintenance since installation and it's all in excellent shape. That equates to around 15k miles' use with chipped k24 and RS2 setups, daily use in the city, Nurburgring trips and other track days. Can't complain at that fir the £70 it cost.

No need to fit the service kit I had but I took the time to do it anyway and apply a liberal amount of red rubber grease to all seals and moving surfaces.

Here's to another 15k of trouble free use

I have the same valve. Checked and greased it recently and still 100% functional with no noticeable wear

All the above was with one big * at the end though - the first valve I had leaked around the side port, where it had not been manufactured correctly, so check it all over! I had to argue with them about that but it was replaced and I got the free service kit with the new one as a sorry = #win.

i just recently had a maintenace for 2nd time on its life.it had been done 6-70000kms on clock with GT2871 turbo.i have seen some minimal wear on the piston but so far so good.it's still working like a charm.i had lubed with the
moly grease.the double o-rings are still in a good shape though.

Mostly the issues with those piston type valves take place when really cold. The grease gets sticky and the response time of the valve slows down. At times the sealing also is affected because of higher friction.

Also condensed water freezes when it gets properly cold, this is a common issue on 2.7´s, where valves are directly behind radiator.

Very good point repo - I suppose that would explain why Audi chose a diaphragm design for OE equipment. That and cost will have been contributing factor.
