High performance D03 Valves are rated for 8 gpm (30 L/min). nominal and 15 gpm (57 L/min). maximum flow, at pressures to 5000 psi (350 bar). This high pressure and high flow capability provides great efficiency in a very compact size. 6500 Series HIGH EFFICIENCY OPERATION Explosion Proof 6500 Series Double Solenoid Large internal flow passages, with uniform flow areas throughout the body coring, provide exceptional efficiency. Typical loop pressure drop (open center spool) is a low 98 psi at 8 gpm (7 bar at 30 L/min) nominal 6800 Series 6900 Series flow ( P loop = P A + B T). Hydraulic Piloted Air Piloted SMOOTH, RELIABLE SHIFTING. A four-land spool design assures exceptionally smooth spool travel. Additional outboard lands provide greater support, eliminating spool imbalance.
