CA400 P.A.R.C VALVE (Parking and Air Reservoir Control)
The CA400 P.A.R.C (Parking and Air Reservoir Control) valve provides a
means of admitting and releasing air to and from the spring brake chambers.
The CA400 P.A.R.C valve will service multiples of spring brake chambers, eg.
tri-axles, quads etc. The valve is reservoir mounted and controlled by the
supply line running from the prime mover. All air delivered to and released
from the spring brakes passes through the P.A.R.C valve with only a small
amount of supply line air being exhausted from a valve mounted on the prime
mover.
