The Sun Hydraulics DCEFXRN (DCEFXRN) is a versatile hydraulic valve designed for high-pressure applications, capable of handling up to 5000 psi (350 bar). This two-position, 4-way directional cartridge valve is spring-offset and features a six-port configuration that provides flexibility in connection and flow direction. It offers nine different spool options, allowing customization to meet specific system requirements. The supply port for this model is designated as port 3, while pilot ports 5 and 6 are positively sealed from the work ports, enhancing the system's integrity and preventing leaks between these sections. Each spool type available for the DCEFXRN has unique capacities influenced by flow forces, which are proportional to flow rate and pressure drop across the valve. These forces can impact the valve's ability to shift completely if they overcome the centering spring force, especially in configurations where spools open passages as they spring center. To accommodate different operational needs, higher flow rates can be utilized at reduced pressures. The DCEFXRN also boasts hardened spool and sleeve components that ensure low leakage rates and superior wear characteristics over time. Its construction includes Sun\u2019s floating style design which minimizes potential internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. For installation, this model requires a hex size of 1-1/4 inches (31.8 mm) and an installation torque between 150-160 lbf ft (203-217 Nm). It supports a flow capacity range from 25 to 100 gpm (95 to 380 L/min) and requires a minimum pilot pressure of 125 psi (9 bar) to effectively shift the valve. The maximum leakage at optimal conditions is rated at 2 in\u00b3/min per 1000 psi (30 cc/min per 70 bar).

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.
