Proportional Flow Control, Compensated, Restrictive 2-way Example Schematic 4 `9 [. X# ^3 x# g) o0 ^9 q4 C
Two-ported design providing an infinitely variable flow rate, regardless of load pressure changes in the circuit, available as “normally open” or “normally closed”. ; e2 O6 w; }( J! ]7 Z/ x
Commonly 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).
