The Sun Hydraulics DCFFXTN (DCFFXTN) is a two-position, 4-way directional cartridge valve that offers versatility through its spring-offset, 6-port configuration. This model can be tailored to specific needs with nine different spool options available, allowing for customization in hydraulic systems. The valve features a supply port at port 3 and has the capability to handle pressures up to 5000 psi (350 bar) across all ports, including the x and y pilot ports (port 5 and port 6). Each spool type chosen can influence the valve's capacity due to variations in flow forces, which are dependent on flow rate and pressure drop across the valve. These forces typically oppose the opening of passages, particularly in configurations where passages open as they return to a center position. The DCFFXTN also boasts hardened spool and sleeve components that ensure low leakage rates and high durability against wear. It incorporates Sun Hydraulics' floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining discrepancies. This model requires a minimum pilot pressure of 125 psi (9 bar) to shift the valve and has a maximum leakage rate of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). It supports flow capacities ranging from 50 to 200 gpm (200 to 760 L/min), making it suitable for various hydraulic applications. For installation, the valve uses a hex size of 1-5/8 inches (41.3 mm) and should be torqued between 350 -375 lbf\u00b7ft (474 -508 Nm). The total weight of the model is approximately 3.90 lbs (1.75 kg), and it utilizes Viton seals for enhanced performance under different 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.
