The Sun Hydraulics DCDFXRN (DCDFXRN) is a versatile two-position, 4-way directional cartridge valve, designed to perform in demanding hydraulic systems. This valve features a spring-offset mechanism and offers a selection of nine different spool options, allowing for tailored configurations to meet specific application needs. It operates with a capacity ranging from 11 to 30 gpm (38 to 120 L/min) depending on the spool type chosen, which directly influences its performance by varying flow forces. Constructed with durability in mind, the DCDFXRN includes a hardened spool and sleeve that ensure low leakage rates and high resistance to wear. Its design incorporates Sun's floating style construction which minimizes potential internal binding caused by excessive installation torque or variations in cavity/cartridge machining. This model is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The valve's pilot ports (5 and 6) are positively sealed from the work ports, enhancing its operational integrity. The minimum pilot pressure required to shift the valve is set at 150 psi (10.5 bar), while maximum leakage does not exceed 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). For installation, the valve requires a hex size of 1-1/8 inches (28.6 mm) and an installation torque between 45 - 50 lbf\u00b7ft (61 - 68 Nm). The compact unit weighs approximately .80 lb (0.35 kg), making it easy to handle and integrate into various hydraulic setups.

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.
