HEIGHT CONTROL VALVE
Height Control Valves regulate the mounting
height (ride height) of the suspension.
1.
One height control valve (HCV) is used,
regardless of the number of axles. The air
springs on each side of the trailer are
connected by 9.5 mm (3/8”) minimum
diameter tubing (customer supplied). Care
must be taken to ensure the HCV is
positioned as shown on the installation
drawing for the model being installed.
2.
Care must be taken when installing HCV to
ensure correct ride height is attained.
3.
To set/adjust ride height, simply assemble
the linkage to the desired length to attain
the required ride height.
For maximum strength, it is recommended
that the linkage set screws 16 mm (5/8") be
placed in the end holes of both links.
4.
This suspension uses a height control valve
(HCV) which utilizes a short delay.
5.
Ensure that the air springs and all valves are
plumbed as shown.
6.
The pressure protection valve (PPV) and
filter are installed between the HCV and the
air reservoir.
7.
Using customer supplied materials, connect
the HCV to all air springs using 9.5 mm
(3/8”) diameter tubing. As with any pressure
system, check for leaks and
eliminate leakage, if present.
