Dump Valve advice please?

Postby paulous » Fri 28.06.2013, 23:19

Hi,

I recently bought this Bailey DV24 dump valve on eBay from someone who had removed it from their Elan. It came with a turbo hose and the fitting kit so was really easy to fit :

At first I quite liked the noise, but after a few days (ok minutes) the novelty soon wore off!

Is there any way I can make it queiter?

I'm guessing the answer is probably no, short of wrapping the whole thing in foam - but I'm not sure that would be safe or if it would even work.

I'm wondering however if I could replace it with a Bailey DV30 recirculating dump valve which I think will simply fit on the same samco hose but will then need somewhere to plumb the outlet pipe in to. The logical place obviously is the trash can but I don't really want to cut that so maybe I could just attach a length of hose to a breather filter? Would that work?

Can anyone offer any advice? Is there a better alternative to the DV30 ?

Basically I want a fairly quiet dump valve but don't want to spend a fortune and don't want to get too complicated as my mechanical skills are very limited. I think I can handle a small amount 'whoosh' noise but not the very loud 'whoosh' the DV24 gives.

Thanks,

Paul

There are varieties that allow plumbing the vent to the bottom of the car. People have used K&N style filters on these to suppress noise. Mine has no filter and just vents down.

Vent it back into the air filter/trash can.......:-)

I think you will find you can't make yours quieter as it only vents to atmosphere, I have a dv30 which is a recirculating valve and is almost silent as i vent it back into the trash can

The valve exits the excess air through the 4 cut outs at the end of the fixture at vacuum hose.
If you could cut out and place a coffee can over this area the noise will be baffled.
I have seen a beer can used :shock:
Or get a different valve.

Thanks for the advice so far, I'm thinking recirculating valve is the way to go.

Has anyone fitted the Forge FMDV008?
