The Sun Hydraulics DCDFXHN (DCDFXHN) is a versatile two-position, 4-way directional cartridge valve with a spring-offset configuration. It features six ports, including pilot ports 5 and 6, each capable of handling pressures up to 5000 psi (350 bar). This model offers a selection of nine different spool options that determine the valve's capacity and performance limits, primarily influenced by flow forces which are proportional to flow and pressure drop. These forces play a crucial role in the operation of the valve, particularly in configurations where spools open passages as they spring to the center. The DCDFXHN is designed for robust performance with hardened spool and sleeve that ensure low leakage rates and superior wear characteristics. It also incorporates Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The valve's leakage per path is meticulously listed in its technical data for precision. Key specifications include a flow capacity ranging from 11 to 30 gpm (38 to 120 L/min), a minimum pilot pressure requirement of 150 psi (10.5 bar) for shifting the valve, and maximum leakage at 110 SUS (24 cSt) being limited to 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The DCDFXHN has a compact hex size of 1\u215b inches (28.6 mm) and requires an installation torque between 45 - 50 lbf\u00b7ft (61 - 68 Nm). Weighing just .80 lb (0.35 kg), this model is efficiently designed for easy integration into various hydraulic systems. Notably, cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals, highlighting the importance of selecting the correct seal type based on system fluid composition.

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.
