Flow = L/min. Flow = L/min.
Flow = L/min.
■ Maximum operating pressure = 350 bar.
■ Maximum valve leakage at 24 cSt = 30 cc/min. at 70 bar.
■ Minimum pilot pressure required to shift valve = DCCC: 12 bar, DCDC: 10,5 bar, DCEC, DCFC: 9 bar.
■ Pilot volume displacement = DCCC: 0,33 cc,; DCDC: 0,98 cc,; DCEC: 2,8 cc,; DCFC: 6,9 cc.
■ All ports will accept 350 bar, including the x and y pilot ports (port 5 and port 6).
■ The pilot ports, 5 and 6 are positively sealed from the work ports.
■ The reason for the different capacities, or performance limits, for the different spool configurations are flow forces. Flow
forces are proportional to flow and pressure drop. Typically, they resist the opening of a passage. Spool configurations that
open passages as they spring centre are the most susceptible. If the flow forces due to the flow and pressure conditions
exceed the centring spring force the valve may not shift completely. Higher flows may be used at lower pressures.
