These valves monitor and regulate the rate at which fluids flow in hydraulic systems. The valve is designed to react to fluctuations in pressure within a circuit. When the pressure attains a certain level, the valve will shut or open based on the setting. This relieves high pressure where it occurs in a system. In this way, a balance is attained with other parts of the system. When a mechanical system is not operational, the flow valves prevent the flow of water under the influence of gravity. The valves keep water in a standby mode which prevents its flow within the system. Flow dividers are a type of flow control valve. They receive fluid from one flow source but divide the flow into two or more outputs in a mechanical system. The flow divider may deliver the resultant flows in equal flow rates or maintain a different rate for each output flow.that there are no problems with the replacement. Lift out the old seals with a screwdriver and clean and remaining residue from the cylinder. Replace with new ones from the kit. Place the shaft back in the cylinder and tighten the bolt. Connect back to the lower control arm and replace the tire.
