The Sun Hydraulics DCECXHN (DCECXHN) is a three-position, 4-way directional cartridge valve, characterized by its spring-centered mechanism and a 6-port configuration. This model is designed to handle a maximum operating pressure of 5000 psi (350 bar), with all ports, including the pilot ports (port 5 and port 6), capable of accommodating this pressure level. The valve's capacity ranges from 25 to 100 gpm (95 to 380 L/min), which varies depending on the specific spool type chosen, as different spool configurations affect the flow forces and consequently the performance limits. This model features hardened spool and sleeve for reduced leakage rates and enhanced durability. It also incorporates Sun\u2019s floating style construction that helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The pilot ports are designed to be positively sealed from the work ports, ensuring efficient operation. The DCECXHN is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids, greases, or lubricants as they will cause damage. For installation, this valve requires a torque of between 150 - 160 lbf ft (203 - 217 Nm) and has a hex size of 1\u00bc inches (31.8 mm). The minimum pilot pressure required to shift the valve is specified at 125 psi (9 bar). Leakage per path at maximum conditions is noted at about 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The overall weight of the model is approximately 1.80 lbs (0.80 kg).

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.
