Height control valves

[David Brady]

Folks

I'd like to upgrade my coach to Ridewell's Extreme Air
height control valves. The Ridewell valves come in the
following 3 configurations:

1) No Dump: self explanatory
2) Pressure Dump: pilot pressure (65psi) is required to
exhaust air,
3) Zero Pressure Dump: removing pilot pressure exhausts
air.

Anyone know what the LXi would use? I'm not at the coach
so I can't look for myself, but I'd guess number 3.

Thanks,
David Brady

David,

My vote would be with #2. If your bags were aired up and the aux system leaked
down,
then the dump valves would not dump the bags. However, with #3 valve, they would
dump the bags whenever the aux leaked down.

David,
What are the advantages of the Extreme Air height control valves over
the valves that came with our coaches?

Hi Morey,



Well I've learned that the Ridewell component is an Imediate Response

HCV whereas the Haldex part that we all use is a Controlled Response

HCV. I'm consequently abandoning this effort. What I wanted to do

was to reduce the deadband thereby achieving a more consistent ride

height. The IR of the Ridewell part may result in a poorer ride. The

Haldex CR effectively filters the input so that only prolonged offsets

in ride height are acted upon. Conversely, the Ridewell part will act

on every deflection that exceeds it's 3 deg deadband; i.e., lots of air

movement, (exhaust and intake), which may lead to an overworked air

compressor, and possibly excessive ride height changes at the air

spring and quite possible poorer suspension performance.
