Proportional Flow Control, Compensated, Restrictive 2-way Example Schematic , p5 n7 m% D7 @1 }
Two-ported design providing an infinitely variable flow rate, regardless of load pressure changes in the circuit, available as “normally open” or “normally closed”. : `0 h0 L3 s; Z& |
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). 9 D2 s* g& P s. h) i3 v; `
Flow range: 30-90 l/min [8-24 US gal/min]. ! M, g* p9 |9 O# p" P2 N
Pressure capability up to 260 bar [3,770 psi]. 2 a# m* K- b9 v V3 y4 L
