The Sun Hydraulics DCEFXWN (DCEFXWN) is a two-position, 4-way directional cartridge valve featuring a spring-offset mechanism and a 6-port directional control that can be tailored through nine different spool options. This model is engineered for high-pressure applications, with all ports capable of accommodating up to 5000 psi (350 bar). Unique to this model, the supply port is designated as port 3, and it includes x and y pilot ports (port 5 and port 6) which are positively sealed from the work ports to prevent leakage. The valve\u2019s performance varies with the selected spool type due to flow forces, which are proportional to flow rate and pressure drop. These forces typically oppose the opening of passages, particularly in spools that open passages as they spring center. If flow forces exceed the centering spring force under certain flow and pressure conditions, the valve may not shift completely. However, it can handle higher flows at reduced pressures effectively. Constructed with a hardened spool and sleeve, the DCEFXWN ensures low spool leakage rates and superior wear characteristics. It also incorporates Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a capacity range of 25-100 gpm (95-380 L/min), minimum pilot pressure required for valve shifting at 125 psi (9 bar), maximum valve leakage at 110 SUS (24 cSt) capped at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar), and pilot volume displacement of .17 in\u00b2 (8 cc). The valve has a hex size of 1\u00bc inches (31.8 mm) and requires an installation torque between 150-160 lbf-ft (203-217 Nm). Additionally, it uses a Viton seal kit/cartridge specified under part number: 990063006.

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.
