This valve bolts directly to the portface of the Char-Lynn steering control units. It contains dual shock valves to protect the Char-Lynn steering control unit, hoses, and steering cylinder(s) from excessive system pressure due to sudden shock forces at the vehicle wheels, and prevent such forces from being transmitted to the steering wheel. It also contains a suction valve to help prevent cavitation at the low pressure side of the cylinder. An inlet check valve blocks reversed flow from the load circuit.

Valve must be set to match your pump pressure plus 100 PSI.
