The Sun Hydraulics DCECXNN (DCECXNN) is a three-position, 4-way directional cartridge valve, identified by its spring-centered mechanism and 6-port configuration. This pilot-to-shift valve is versatile in its applications, accommodating a wide range of spool options that dictate its capacity and performance limits. Each port, including the x and y pilot ports (port 5 and port 6), can withstand pressures up to 5000 psi (350 bar). The valve's performance varies with different spool configurations due to flow forces, which are influenced by flow rate and pressure drop across the valve. These forces can resist the opening of passages, especially in configurations where passages open as they return to the center. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a flow capacity ranging from 25 to 100 gpm (95 to 380 L/min), and minimal leakage rates for each path. The minimum pilot pressure required to shift the valve is set at 125 psi (9 bar). Designed for durability and reliability, the DCECXNN features hardened spool and sleeve components that ensure consistent performance with low leakage rates and superior wear characteristics. Additionally, it incorporates Sun\u2019s floating style construction which minimizes internal binding caused by excessive installation torque or variations in cavity/cartridge machining. This model also supports environmental adaptability with cartridges configured with EPDM seals specifically for use in systems utilizing phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. With a model weight of approximately 1.80 lbs (0.80 kg), it also specifies installation requirements such as a hex size of 1-1/4 inches (31.8 mm) and an installation torque between 150 -160 lbf\u00b7ft (203 -217 Nm). This makes the DCECXNN an essential component for hydraulic systems requiring high-pressure capabilities and precise fluid control.

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.
