The Sun Hydraulics DCDFXBN (DCDFXBN) is a two-position, 4-way directional cartridge valve, designed for robust hydraulic system applications. This valve features a spring-offset configuration and offers the flexibility of nine different spool options to cater to various operational demands. Each spool configuration is tailored for specific flow and pressure requirements, with the capacity to handle pressures up to 5000 psi (350 bar) across all ports, including the pilot ports (port 5 and port 6). The DCDFXBN model incorporates hardened spool and sleeve components that ensure low leakage rates and high wear resistance, crucial for maintaining efficiency and longevity in demanding environments. The valve is engineered with Sun\u2019s floating style construction which helps minimize internal part binding that can occur due to excessive installation torque or cavity/cartridge machining variations. This model operates within a flow capacity range of 11 to 30 gpm (38 to 120 L/min), requiring a minimum pilot pressure of 150 psi (10.5 bar) for valve shifting. It is designed with EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The maximum leakage specification for this valve is quantified at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar), ensuring efficient operation even under high-pressure conditions. Additional technical specifications include a pilot volume displacement of approximately 0.06 in\u00b3 (0.98 cc), a hex size requirement of 1-1/8 in. (28.6 mm) for the valve, and an installation torque ranging between 45-50 lbf\u00b7ft (61-68 Nm). The overall weight of the DCDFXBN model is relatively light at about 0.80 lb (0.35 kg), facilitating easier handling and installation in various system configurations.

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.
