Integral valves are available
for the Char-Lynn steering
control unit. Included are:
Inlet Relief Valve, Cylinder
Port Shock Valves, LS-Relief
Valve, and Anti-Cavitation
Valves for cylinder ports. In
addition, a Manual Steering
Check Valve for limited
manual steering is included.
The integral valves eliminate
the need for a separate
valve block, and provides
versatility to meet any
steering circuit standard.
Valve Description:
1 Anti-cavitation check
valve for cylinder ports—
(R & L) protects steering
circuit against vacuum
(cavitation) conditions.
2 Cylinder Port Relief
Valves—(R & L) protects
hoses against pressure
surge created by ground
forces on the steered axle.
3 Manual Steering Check
Valve—converts unit to a
hand operated pump for
limited manual steering.
Included in all units except
Series 20, 25, and 40.**
4 Inlet Relief Valve—limits
maximum pressure drop
across the steering unit
protecting the steering
circuit.
5 Inlet Check Valve—
prevents oil from returning
through the steering unit
when pressure on the
cylinder side is greater
than pressure on the inlet
side to prevent steering
wheel kick.
6 LS-Relief Valve—Limits
maximum pressure in the
steering circuit (LS units
only)
**Steering units with displacements larger than
185 cm 3 /r [11.3 in 3 /r] may require a separate
power source for limited operation.
