The Sun Hydraulics DCFFXYN (DCFFXYN) is a versatile two-position, 4-way directional cartridge valve designed for high-pressure hydraulic systems. This model features a spring-offset mechanism and six ports, including pilot ports (port 5 and port 6) which are positively sealed from the work ports to prevent leakage. Each port can withstand pressures up to 5000 psi (350 bar), making it suitable for robust applications. The DCFFXYN offers a choice of nine different spool options, allowing customization based on specific flow force requirements and operational conditions. These spool configurations play a crucial role in determining the valve's capacity, which ranges from 50 to 200 gpm (200 to 760 L/min). The valve's performance is influenced by flow forces\u2014forces proportional to flow and pressure drop\u2014which can affect the shifting of the valve if they exceed the force of the centering spring, particularly in configurations where passages open as they spring center. For installations requiring precise control and reliability, this model incorporates Sun\u2019s floating style construction that minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It also features a hardened spool and sleeve that ensure low leakage rates and superior wear characteristics. The minimum pilot pressure required to shift the valve is 125 psi (9 bar), while maximum leakage at 110 SUS (24 cSt) does not exceed 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The DCFFXYN has an installation torque range between 350-375 lbf\u00b7ft (474-508 Nm) and weighs approximately 3.90 lb (1.75 kg). This model uses Viton seals for enhanced performance under varying 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.
