The Sun Hydraulics DCDFXAV (DCDFXAV) is a two-position, 4-way directional cartridge valve, characterized by its spring-offset and 6-port configuration. This model can be tailored to specific needs through a selection of nine different spool options, each affecting the valve's capacity and performance limits based on flow forces which are proportional to flow and pressure drop. The DCDFXAV features a supply port at port 3, with all ports capable of accommodating pressures up to 5000 psi (350 bar), including the x and y pilot ports (port 5 and port 6). The valve's performance varies with different spool configurations due to these flow forces; configurations that open passages as they spring center are particularly susceptible to incomplete shifting if flow forces exceed the spring force. It allows for higher flows at lower pressures to adapt to varied application needs. Each leakage path is specifically documented in its technical data for precision and reliability in performance. Constructed with hardened spool and sleeve, the DCDFXAV ensures low leakage rates and high wear resistance, enhancing its durability. The model also incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. The cartridges configured with EPDM seals are designated for systems using phosphate ester fluids, avoiding exposure to petroleum-based substances which could damage the seals. Additional specifications include a flow capacity range from 11-30 gpm (38-120 L/min), minimum pilot pressure required at 150 psi (10.5 bar), and maximum valve leakage quantified at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The DCDFXAV weighs approximately 0.80 lb (0.35 kg) and features a hex size of 1-1/8 inches (28.6 mm) with an installation torque between 45-50 lbf-ft (61-68 Nm). This model proves essential for applications requiring reliable hydraulic direction control under varying pressures and flows.

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.
