The Sun Hydraulics DCFFXWN (DCFFXWN) is a versatile hydraulic valve designed for high-pressure applications. This two-position, 4-way directional cartridge is spring-offset and features six ports, including pilot ports (port 5 and port 6) that are positively sealed from the work ports. With a capacity ranging from 50 to 200 gpm (200 to 760 L/min), the valve can handle pressures up to 5000 psi (350 bar). The choice of nine different spool options allows customization according to specific flow force requirements, which vary based on spool configuration and are critical in determining the valve's performance limits. Key specifications include a minimum pilot pressure requirement of 125 psi (9 bar) for valve shifting, and a maximum leakage rate at 110 SUS (24 cSt) of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The valve's robust construction features a hardened spool and sleeve which ensure low leakage rates and high wear resistance. Additionally, it incorporates Sun\u2019s floating style construction to minimize internal part binding due to installation torque or cavity/cartridge machining variations. The DCFFXWN has an installation torque range of 350-375 lbf\u00b7ft (474-508 Nm) and weighs approximately 3.90 lb (1.75 kg). It is designed with a hex size of 1\u215d inches (41.3 mm), facilitating easy installation. The seal kit for this model uses Viton components, ensuring durability and reliability in various operating environments. This hydraulic valve is ideal for applications requiring precise control over fluid handling in high-pressure systems.

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.
- 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.
