In-Line Flow Con-trol Operation

Application of In-Line Flow Control

Oil flow entering the In-line Flow Control passes through the fixed orifice in theplunger, then out the cross holes in the plunger and sleeve. The oil then flowsaround the sleeve and out the Flow Control. When the oil flows through the fixedorifice it creates a pressure differential across the fixed orifice. As oil flow volumeincreases the pressure differential increases. This pressure differential causes theplunger to move, compressing the spring and gradually closing off the cross holes.The spring rate and cross hole design causes a restriction that regulates the predeter-mined flow rate of the flow Control. This Flow Control is regulated flow in onedirection and free flow in the opposite direction. The Flow Control is flow sensitiveand not pressure sensitive. The flow rate is factory set and is not field adjustable.

Hydrostatic Limited Slip Differential - Used to prevent over speed of Hydraulic Motorswhen two motors are teed together. By installing one in each motor work port, it willcontrol maximum flow in both directions.

Motor Over speed from external over run - Used in motor outlet port to prevent anexternal load from causing the motor to over speed.

Controlled Flow to Hydraulic circuit - Used in multiple circuits to control maximumflow to or from a single hydraulic circuit.

Speed Control for Multiple motors connected in parallel - Used to control flow rate toindividual motors to allow all motors to turn at the same speed regardless of load onmotor.
