Proportional Flow Control, Compensated, Restrictive 2-way Example Schematic & w" |7 h; Q6 w& F' ?
Two-ported design providing an infinitely variable flow rate, regardless of load pressure changes in the circuit, available as “normally open” or “normally closed”.
. y5 q2 {0 ^2 m2 P: m' D! pCommonly 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).
" ]* Q8 _6 h6 @ w9 GFlow range: 30-90 l/min [8-24 US gal/min].
