The Sun Hydraulics DCFFXRV (DCFFXRV) is a versatile two-position, 4-way directional cartridge valve featuring spring-offset and 6-port directional configurations. It is designed to accommodate a variety of nine different spool options, each providing unique capacity and performance characteristics influenced by flow forces which are proportional to flow and pressure drop. This valve\u2019s design includes hardened spool and sleeve that ensure low leakage rates and superior wear characteristics, enhancing its durability and reliability in various applications. The DCFFXRV operates effectively with all ports capable of accepting up to 5000 psi (350 bar), including the pilot ports (port 5 and port 6), which are positively sealed from the work ports to prevent leakage. The valve\u2019s performance is also supported by Sun's floating style construction, minimizing internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a flow capacity ranging between 50-200 gpm (200-760 L/min) and requiring a minimum pilot pressure of 125 psi (9 bar) to shift, this model is adaptable for high-demand systems. The maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Additional technical specifications include a pilot volume displacement of .42 in\u00b3 (6.9 cc), a hex size for the valve at 1-5/8 inches (41.3 mm), and an installation torque range between 350-375 lbf-ft (474-508 Nm). The model weighs approximately 3.90 lbs (1.75 kg), ensuring it is robust yet manageable for installation and maintenance processes. This product utilizes Viton seals, indicated by the seal kit/cartridge number: Viton: 990064006, ensuring high resistance against various types of fluids and environmental 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.
