The Sun Hydraulics DCFCXWN (DCFCXWN) is a three-position, 4-way directional cartridge valve which operates as a spring-centered, 6-port directional valve. This model is designed to handle a maximum operating pressure of 5000 psi (350 bar) across all ports, including the pilot ports (port 5 and port 6). The DCFCXWN offers various spool options that dictate the valve's capacity, influenced by flow forces which are proportional to flow and pressure drop. These forces can impact the shifting of the valve, especially under conditions where they exceed the centering spring force. This model features hardened spool and sleeve for enhanced durability and consistent low spool leakage rates. It also incorporates Sun's floating style construction which helps minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The DCFCXWN is suitable for systems using phosphate ester fluids when configured with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. Key technical specifications include a flow capacity range of 50-200 gpm (200-760 L/min), minimum pilot pressure required to shift the valve at 125 psi (9 bar), and maximum valve leakage at 110 SUS (24 cSt) rated at 2 in\u00b3/min per 1000 psi (30 cc/min per 70 bar). The pilot volume displacement is approximately .42 in\u00b3 (6.9 cc), with a hex size for the valve at 1-5/8 inches (41.3 mm) and an installation torque requirement between 350-375 lbf-ft (474-508 Nm). The model weighs around 3.80 lb (1.75 kg). Each cartridge is available with an optional Viton seal kit under part number: 990064006.

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.
