The Sun Hydraulics DCDFXTN (DCDFXTN) is a versatile hydraulic component designed for high-pressure applications, capable of handling up to 5000 psi (350 bar). This two-position, 4-way directional cartridge valve features a spring-offset configuration and offers a selection of nine different spool options, allowing customization based on specific flow and pressure needs. The valve\u2019s unique construction includes hardened spool and sleeve to ensure low leakage rates and exceptional wear characteristics. It also incorporates Sun\u2019s floating style construction to reduce risks of internal parts binding due to installation torque or variations in cavity/cartridge machining. Each path's leakage is specifically noted in the technical data, ensuring precise operation for critical applications. The pilot ports (5 and 6) are positively sealed from the work ports, enhancing the valve's performance reliability. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be used with petroleum-based fluids as they can damage the seals. The DCDFXTN operates efficiently within a capacity range of 11-30 gpm (38-120 L/min), requiring a minimum pilot pressure of 150 psi (10.5 bar) to shift the valve. The maximum leakage at 110 SUS (24 cSt) is maintained at 2 in\u00b3/min per 1000 psi (30 cc/min per 70 bar). The model is compact and lightweight at just .80 lb (0.35 kg), making it suitable for various installations without adding significant weight or bulk. Installation specifications include a valve hex size of 1-1/8 inches (28.6 mm) and an installation torque between 45-50 lbf\u00b7ft (61-68 Nm), ensuring secure and straightforward setup in hydraulic 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.
- 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.
