The Sun Hydraulics DCFCXTN (DCFCXTN) is a versatile hydraulic control valve designed for high-pressure applications. This three-position, 4-way directional cartridge is spring-centered and includes six ports, with the supply port designated as port 3. Each port can withstand pressures up to 5000 psi (350 bar), making it suitable for a wide range of hydraulic systems. The DCFCXTN features various spool options that influence the valve's capacity and performance by affecting flow forces, which are proportional to flow and pressure drop. These forces typically resist the opening of a passage, particularly in configurations where spools open passages as they spring center. The valve's pilot ports (5 and 6) are positively sealed from the work ports, ensuring efficient operation and preventing leakage between these sections. Designed with hardened spool and sleeve, the DCFCXTN provides consistent low spool leakage rates and exhibits excellent wear characteristics. It incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity ranging from 50 to 200 gpm (200 to 760 L/min), minimum pilot pressure required to shift the valve at 125 psi (9 bar), and maximum operating pressure of 5000 psi (350 bar). The valve also features a maximum leakage rate of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). For installations, the valve requires a hex size of 1-5/8 inches (41.3 mm) and an installation torque between 350 -375 lbf\u00b7ft (474 -508 Nm). The model weighs approximately 3.80 lbs (1.75 kg). Cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Overall, the DCFCXTN offers robust performance for complex hydraulic systems requiring precise control under high-pressure conditions.

Three-position, 4-way directional cartridges are spring-centered, 6-port directional valves that can be configured from a choice of 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.
