The Sun Hydraulics DCEFXHV (DCEFXHV) is a two-position, 4-way directional cartridge valve designed with versatility and high-performance standards in mind. This spring-offset, 6-port directional valve can be customized with one of nine different spool options to suit various application needs. It features a maximum operating pressure of 5000 psi (350 bar) for all ports, including the pilot ports (port 5 and port 6), ensuring robust performance even under high-pressure conditions. The valve's capacity and performance vary depending on the chosen spool configuration, primarily due to flow forces which are influenced by flow rate and pressure drop across the valve. These forces can impact the shifting behavior of the valve, particularly in configurations where spool movements open passages. To counteract these forces and prevent incomplete shifting, configurations that allow higher flows at lower pressures may be necessary. Each flow path within the DCEFXHV exhibits minimal leakage, as specified in its technical data, ensuring efficient operation and reduced fluid loss. The pilot ports are designed to be positively sealed from the work ports, enhancing the valve\u2019s overall reliability and performance. Constructed with a hardened spool and sleeve, the DCEFXHV offers low leakage rates and exceptional wear characteristics. It also incorporates Sun\u2019s floating style construction which minimizes internal part binding that could result from excessive installation torque or variations in cavity/cartridge machining. This model is suitable for applications requiring precise control of hydraulic flow with capacities ranging between 25 to 100 gpm (95 to 380 L/min). Additional technical specifications include a minimum pilot pressure requirement of 125 psi (9 bar) for valve shifting, a maximum leakage rate at specific conditions, pilot volume displacement specifications, as well as installation details like valve hex size and recommended torque settings.

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.
