The Sun Hydraulics DCDFXXN (DCDFXXN) is a two-position, 4-way directional cartridge valve that offers versatile performance with its spring-offset, 6-port configuration. This model can be customized using one of nine different spool options according to specific application needs. The valve's robust design allows all ports, including the pilot ports (port 5 and port 6), to handle pressures up to 5000 psi (350 bar). Each spool type impacts the valve's capacity by influencing flow forces, which are proportional to flow and pressure drop and may resist the opening of passages under certain conditions. The DCDFXXN features hardened spool and sleeve components that ensure low leakage rates and superior wear characteristics, enhancing durability and reliability in demanding environments. It also incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue arising from excessive installation torque or cavity/cartridge machining variations. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as it can damage the seals. The technical specifications of this model include a flow capacity range of 11-30 gpm (38-120 L/min), a minimum pilot pressure requirement of 150 psi (10.5 bar) for valve shifting, and maximum leakage at 110 SUS (24 cSt) capped at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Additional features like a pilot volume displacement of .06 in\u00b3 (0.98 cc), a hex size for the valve at 1-1/8 inches (28.6 mm), and an installation torque between 45-50 lbf\u00b7ft (61-68 Nm), make this model highly functional for various hydraulic applications. The unit weighs approximately .80 lb (0.35 kg), ensuring it is both sturdy and manageable for integration into various systems.

Two-position, 4-way directional cartridges are spring-offset, 6-port directional valves that can be configured from a choice of 9 different spool options. The supply port is port 3 and all ports will accept 5000 psi (350 bar). Capacity for these pilot-to-shift valves is dependent on the spool type specified.
- All ports will accept 5000 psi (350 bar), including the x and y pilot ports (port 5 and port 6).
- 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 center are the most susceptible. If the flow forces due to the flow and pressure conditions exceed the centering spring force the valve may not shift completely. Higher flows may be used at lower pressures.
- Leakage listed in technical data is for each path.
- The pilot ports, 5 and 6, are positively sealed from the work ports.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Hardened spool and sleeve provide consistent and low spool leakage rates and excellent wear characteristics.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
