The Sun Hydraulics DCFFXAV (DCFFXAV) is a versatile two-position, 4-way directional cartridge valve, designed for robust hydraulic system applications. This spring-offset, 6-port directional valve can be customized with one of nine different spool options to meet specific operational requirements. Each port, including the pilot ports (port 5 and port 6), can handle pressures up to 5000 psi (350 bar). The DCFFXAV's performance varies based on the chosen spool type due to flow forces, which are influenced by flow rate and pressure drop across the valve. Key specifications include a flow capacity range of 50 to 200 gpm (200 to 760 L/min), with a minimum pilot pressure requirement of 125 psi (9 bar) necessary for shifting the valve. The maximum leakage at full pressure is noted as 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The valve features hardened spool and sleeve components that ensure low leakage rates and high durability against wear. The design incorporates Sun\u2019s floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. This feature enhances overall reliability and performance consistency. Installation specifications include a hex size of 1\u215d inches (41.3 mm) and an installation torque range of 350 to 375 lbf\u00b7ft (474 to 508 Nm). The unit weighs approximately 3.90 lbs (1.75 kg). This model is particularly suitable for applications requiring reliable directional control in hydraulic systems, ensuring efficient operation even under high-pressure conditions while maintaining tight seals between pilot and work ports.

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.
