The Sun Hydraulics DCDFXYN (DCDFXYN) is a two-position, 4-way directional cartridge valve, characterized by its spring-offset, 6-port configuration. This model can be tailored to specific needs through a selection of 9 different spool options. The primary supply port for this valve is designated as port 3, and it can handle pressures up to 5000 psi (350 bar). The DCDFXYN\u2019s performance varies depending on the chosen spool type due to flow forces which are influenced by flow rate and pressure drop across the valve. These forces typically act against the opening of passages, particularly in configurations where passages open as they return to a center position. The valve features pilot ports (ports 5 and 6) that are positively sealed from the work ports to prevent cross-contamination. Each flow path within the valve exhibits minimal leakage, with maximum leakage specifications provided at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The DCDFXYN employs hardened spool and sleeve components which ensure low leakage rates and high durability against wear. For hydraulic systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these seals must not be exposed to petroleum-based fluids which would cause damage. Additionally, Sun Hydraulics incorporates its floating style construction into this model to reduce the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This model requires a minimum pilot pressure of 150 psi (10.5 bar) to shift the valve and has a flow capacity ranging from 11 to 30 gpm (38 to 120 L/min). Installation specifications include a hex size of 1-1/8 inches (28.6 mm) and an installation torque between 45-50 lbf-ft (61-68 Nm). The unit itself weighs approximately .80 lb (0.35 kg), making it manageable for various applications while maintaining robust performance and reliability in demanding operational 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
