Proportional Flow Control, Compensated, Restrictive 2-way Example Schematic
# h3 H9 V6 |, h3 YTwo-ported design providing an infinitely variable flow rate, regardless of load pressure changes in the circuit, available as “normally open” or “normally closed”. & w. p) g! A$ y/ T
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).
