The Sun Hydraulics DCFFXXV (DCFFXXV) is a high-performance, two-position, 4-way directional cartridge valve that features a spring-offset, 6-port configuration. This versatile valve can be customized with one of nine different spool options to meet specific application requirements. Each spool type affects the valve's capacity, which is influenced by flow forces\u2014forces that are proportional to both flow and pressure drop and can impact the valve\u2019s shifting ability under certain conditions. Designed for robust operation, the DCFFXXV can handle up to 5000 psi (350 bar) across all its ports, including the pilot ports (port 5 and port 6). This model boasts a hardened spool and sleeve which not only reduce leakage but also enhance wear characteristics significantly. The incorporation of Sun\u2019s floating style construction minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. 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) needed to shift the valve. It also features a maximum leakage rate at 110 SUS (24 cSt) of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The DCFFXXV is designed for easy installation with a hex size of 1-5/8 inches (41.3 mm) and an installation torque range of 350 -375 lbf\u00b7ft (474 -508 Nm). Weighing in at approximately 3.90 lbs (1.75 kg), this model ensures reliability and performance for various hydraulic applications.

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.
