The Sun Hydraulics DCEFXHN (DCEFXHN) is a high-performance, two-position, 4-way directional cartridge valve characterized by its spring-offset and 6-port configuration. This valve can be customized with one of nine different spool options according to specific application needs. Each port, including the x and y pilot ports (port 5 and port 6), can withstand pressures up to 5000 psi (350 bar). The capacity of these pilot-to-shift valves varies based on the spool type chosen, which affects the flow forces\u2014forces that are proportional to flow and pressure drop and typically resist the opening of a passage. Key features include a hardened spool and sleeve that ensure low leakage rates and superior wear characteristics. Additionally, the DCEFXHN utilizes Sun\u2019s floating style construction which minimizes internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. This valve is designed for use in systems requiring reliable directional control of hydraulic fluids at high pressures. It supports flow capacities ranging from 25 to 100 gpm (95 to 380 L/min) and requires a minimum pilot pressure of 125 psi (9 bar) to shift the valve effectively. The maximum leakage at operational conditions is rated at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Installation specifications include a valve hex size of 1-1/4 inches (31.8 mm) and an installation torque between 150-160 lbf-ft (203-217 Nm). For maintenance or replacement, a Viton seal kit is recommended, specifically part number: 990063006. Overall, the DCEFXHN offers robust performance suitable for demanding applications where precise control of hydraulic flow is critical under varying pressures and flow 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.
