Proportional Flow Control, Compensated, Restrictive 2-way Example Schematic 5 B6 o3 M- j. n" d
Two-ported design providing an infinitely variable flow rate, regardless of load pressure changes in the circuit, available as “normally open” or “normally closed”.
3 _ q' E* _2 K7 \ LCommonly used for variable meter-in or meter-out circuits to control actuator speeds or for controlling flow to a complete circuit, where compensation is required (load-independent flow).
