Proportional Flow Control, Compensated, Restrictive 2-way Example Schematic - M5 @2 @4 N% C0 O+ S% r
Two-ported design providing an infinitely variable flow rate, regardless of load pressure changes in the circuit, available as “normally open” or “normally closed”. 1 [& l) |& n/ t- h) _, F
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). ; M+ F7 j0 N4 D9 a7 M4 a
Flow range: 30-90 l/min [8-24 US gal/min].
