Water Quantity Control Valve for WABCO

The role of the water  quantity control valve to limit the maximum flow of the steering pump, the flow control valve is an actuator, the flow control valve is generally in the oil pump, the flow of the steering pump is proportional to the gear speed (engine speed), the steering pump even when the engine is idling, the flow can also ensure the maximum moving speed of the power cylinder piston required for rapid steering. When the engine speed is high, the flow rate of the oil pump will be too large, resulting in excessive power consumption of the oil pump and high oil temperature.
