The Sun Hydraulics DCDFXWN (DCDFXWN) is a two-position, 4-way directional cartridge featuring spring-offset, 6-port directional valves that can be customized with one of nine different spool options. This model is designed to handle a supply port at port 3, with all ports capable of accepting up to 5000 psi (350 bar). The DCDFXWN's performance varies based on the spool type chosen due to flow forces, which are proportional to flow and pressure drop and typically resist the opening of a passage. Spools that open passages as they spring center are most susceptible to these forces. The valve's capacity ranges from 11 to 30 gpm (38 to 120 L/min), and it requires a minimum pilot pressure of 150 psi (10.5 bar) for shifting. Each path's leakage is meticulously detailed in the technical data, ensuring precise performance standards are met. The pilot ports (5 and 6) are positively sealed from the work ports, enhancing the valve\u2019s reliability and efficiency in various hydraulic systems. Notably, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The DCDFXWN benefits from hardened spool and sleeve components that ensure low leakage rates and superior wear characteristics over time. Additionally, it incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This model also features a hex size of 1-1/8 inches (28.6 mm) and requires an installation torque between 45 - 50 lbf ft (61 - 68 Nm). Weighing just .80 lb (0.35 kg), this compact yet robust valve integrates seamlessly into various hydraulic systems requiring reliable directional control under high-pressure conditions.

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.
