The Sun Hydraulics DCEFXTN (DCEFXTN) is a versatile two-position, 4-way directional cartridge valve, designed for high-pressure hydraulic systems. It features a spring-offset mechanism and offers a selection of nine different spool options to cater to diverse application needs. Each spool configuration is tailored to handle specific flow forces, which are influenced by flow rates and pressure drops across the valve. This customization ensures optimal performance by aligning with the operational demands of various hydraulic systems. This model operates efficiently under a maximum pressure of 5000 psi (350 bar), applicable to all its ports, including the pilot ports (port 5 and port 6). The DCEFXTN is engineered with hardened spool and sleeve components that ensure minimal leakage, consistent performance, and superior wear resistance over time. The innovative Sun floating style construction incorporated into this model minimizes potential internal binding caused by excessive installation torque or variances in cavity/cartridge machining. Key specifications include a flow capacity ranging from 25 to 100 gpm (95 to 380 L/min), requiring a minimum pilot pressure of 125 psi (9 bar) for valve shifting. Leakage performance is maintained at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The valve's hex size is set at 1\u00bc inches (31.8 mm) with an installation torque requirement between 150 to 160 lbf\u00b7ft (203 to 217 Nm). For maintenance or repairs, it uses a Viton seal kit/cartridge specified as part number: 990063006. This combination of features makes the DCEFXTN suitable for high-performance hydraulic applications demanding reliability and precision under variable operational conditions.

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.
