The Sun Hydraulics DCFFXYV (DCFFXYV) is a two-position, 4-way directional cartridge valve featuring a spring-offset, 6-port configuration. This valve can be tailored with one of nine different spool options according to specific application needs. It is designed to handle a maximum pressure of 5000 psi (350 bar) across all ports, including the pilot ports (port 5 and port 6). The performance of the DCFFXYV varies with different spool configurations due to flow forces, which are influenced by both flow rate and pressure drop. These forces typically resist the opening of passages, with spools that open passages as they spring center being most affected. This model incorporates hardened spool and sleeve components which ensure low leakage rates and high durability under wear. Additionally, the DCFFXYV uses Sun Hydraulics' floating style construction which minimizes internal part binding that could result from excessive installation torque or variations in cavity/cartridge machining. The valve's technical specifications include a flow capacity range of 50 to 200 gpm (200 to 760 L/min), a minimum pilot pressure requirement of 125 psi (9 bar) for shifting the valve, and maximum leakage at 110 SUS (24 cSt) capped at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The physical dimensions feature a hex size of 1-5/8 inches (41.3 mm) and an installation torque between 350 to 375 lbf\u00b7ft (474 to 508 Nm). The total weight of the model is approximately 3.90 lbs (1.75 kg). For maintenance or repairs, a Viton seal kit is available under part number: 990064006.

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.
