The Sun Hydraulics DCECXAV (DCECXAV) is a three-position, 4-way directional cartridge valve that is spring-centered and features six ports capable of handling pressures up to 5000 psi (350 bar). This model offers flexibility through various spool options which dictate the valve\u2019s capacity and performance limits. The flow forces, which are proportional to flow and pressure drop, play a crucial role in the operation of these valves. Particularly, spool configurations that open passages while spring-centering are more susceptible to these forces, potentially affecting the complete shifting of the valve under certain conditions. The DCECXAV model ensures that all ports, including the pilot ports (port 5 and port 6), can withstand maximum operating pressures. These pilot ports are also positively sealed from the work ports to prevent leakage. The valve's construction incorporates Sun\u2019s floating style design which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity range from 25 to 100 gpm (95 to 380 L/min), with a minimum pilot pressure requirement of 125 psi (9 bar) for valve shifting. The maximum allowable leakage at operational conditions is notably low at 2 in\u00b3/min per 1000 psi (30 cc/min per 70 bar). For installation, the valve has a hex size of 1-1/4 inches (31.8 mm) and requires an installation torque between 150-160 lbf-ft (203-217 Nm). The overall weight of this model is approximately 1.80 lbs (0.80 kg). The DCECXAV cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. This model also features hardened spool and sleeve components that offer excellent wear characteristics along with consistent and low leakage rates, enhancing both durability and performance reliability in various hydraulic applications.

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.
