The Sun Hydraulics DCFCXXN (DCFCXXN) is a high-performance, three-position, 4-way directional cartridge valve. This spring-centered unit is designed to handle a maximum operating pressure of 5000 psi (350 bar) across all its ports, including the X and Y pilot ports (port 5 and port 6). The valve's functionality and capacity vary depending on the specified spool type, which influences its response to flow forces\u2014forces that are proportional to flow rate and pressure drop and can impact the valve's shifting ability under certain conditions. This model features hardened spool and sleeve components that ensure low leakage rates and superior wear characteristics, enhancing durability and reliability in demanding applications. It also incorporates Sun's unique floating style construction, which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. The DCFCXXN supports a flow capacity ranging from 50 to 200 gpm (200 to 760 L/min), with a minimal pilot pressure requirement of 125 psi (9 bar) for valve shifting. Leakage specifications for this model are meticulously detailed, with a maximum valve leakage at 110 SUS (24 cSt) being 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Additionally, the cartridge is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids, greases, or lubricants as they can cause damage. This model's practical design includes a hex size of 1-5/8 inches (41.3 mm) and requires an installation torque between 350 -375 lbf\u00b7ft (474 -508 Nm). The overall weight of the DCFCXXN model is approximately 3.80 lbs (1.75 kg), ensuring it is robust yet manageable for installation and maintenance activities.

Three-position, 4-way directional cartridges are spring-centered, 6-port directional valves that can be configured from a choice of 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.
