OPERATION
MOUNTING ORIENTATION
The SDS-9600 ™ trailer suspension dump valve is mounted
to the trailer frame rail or cross-member. It is preferred that
the valve be mounted on the backside of a cross-member
with the exhaust port facing down. Mounting on the top side
of a cross-member is acceptable, provide the exhaust port
is facing rearward on the vehicle. Never mount the valve
with the exhaust port facing upwards. The valve should
have at least 2 inches of clearance between the exhaust
port and any other surface. Refer to Figure 2.
PREVENTIVE MAINTENANCE
Important: The SDS-9600 ™ control brake valve is not
serviceable, but must be inspected for proper operation
as a part of routine vehicle maintenance.
No two vehicles operate under identical conditions, as
a result, maintenance intervals may vary. Experience is
a valuable guide in determining the best maintenance
interval for air brake system components. At a minimum,
the SDS-9600
™ valve should be inspected every 6 months
or 1500 operating hours, whichever comes fi rst, for proper
operation. Should it not meet the elements of the operational
tests noted in this document, further investigation and
replacement of the valve may be required.
REMOVAL
Secure the vehicle with spring brakes or blocks. Drain the
reservoir which supplies the SDS-9600
™ valve. Mark and
disconnect the connecting air lines. Remove the screws
that secure the valve to the trailer frame rail. Remove the
valve.
INSTALLATION
Typical system schematics for the SDS-9600 ™ valve are
shown in Figures 3 and 4.
Inspect the mounting hardware and replace if necessary.
Check connecting air lines for integrity and foreign material,
replace if necessary. Re-connect the air lines.. Check the
operation of valve by charging system and performing the
service check as described in this manual.
