The Sun Hydraulics DCFFXWV (DCFFXWV) is a versatile two-position, 4-way directional cartridge valve featuring a spring-offset, 6-port configuration that can be tailored with one of nine different spool options. This pilot-to-shift valve is primarily designed for high-pressure applications, with all ports capable of handling up to 5000 psi (350 bar). The DCFFXWV is distinguished by its robust construction which includes a hardened spool and sleeve that ensure low leakage rates and exceptional wear characteristics. This model incorporates Sun\u2019s floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. It offers a flow capacity ranging from 50 to 200 gpm (200 to 760 L/min), and requires a minimum pilot pressure of 125 psi (9 bar) for shifting the valve. The maximum leakage at high pressure conditions is limited to 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Additional features include positively sealed pilot ports (ports 5 and 6) from the work ports, providing reliable operation under various conditions. The DCFFXWV also supports a pilot volume displacement of approximately .42 in\u00b3 (6.9 cc), and it can be installed using a specific torque range of 350 to 375 lbf\u00b7ft (474 to 508 Nm). It has an overall weight of about 3.90 lb (1.75 kg), making it suitable for various hydraulic systems without adding significant weight. The valve\u2019s dimensions facilitate ease of installation with a hex size of 1-5/8 inches (41.3 mm). This model is compatible with Viton seal kits, specifically part number: 990064006, ensuring enhanced durability and chemical resistance for diverse operational environments.

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.
