Searching for a low dB recirculating valve

[niko]

I have an upgraded recirculating valve (the bosh one with copper insert) but i can't anymore support the hooting sound...
Does anybody know one strong recirculating valve that isn't so noisy ?

I run a turbo xs and I can't hear it at all a bit pricey though $180 US.

Thanks for the answer.
But i was looking for something less expensive, it's a bit pricey just to avoid the bad noisy effect...
Anyway, is the mounting difficult ?
There is different model (i saw this at www..se) :
1/ TypS
2/ TypH
3/ Bigger TypeH
4/ Typ XS

Is the TypH the one i need ?
