The Sun Hydraulics DCECXHV (DCECXHV) is a versatile three-position, 4-way directional cartridge valve featuring spring-centered operation and a six-port configuration. This pilot-to-shift valve is capable of handling pressures up to 5000 psi (350 bar) across all ports, including the x and y pilot ports (port 5 and port 6). The performance of the DCECXHV varies with different spool options due to flow forces which are proportional to flow and pressure drop. These forces may resist the opening of passages, affecting the valve\u2019s shifting ability under certain flow and pressure conditions. The DCECXHV features hardened spool and sleeve components that ensure low leakage rates, excellent wear characteristics, and consistent performance. It incorporates Sun's floating style construction designed to minimize internal parts binding which could be caused by excessive installation torque or variations in cavity/cartridge machining. This model uses EPDM seals configured for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. The valve offers a flow capacity ranging from 25 to 100 gpm (95 to 380 L/min), requires a minimum pilot pressure of 125 psi (9 bar) for shifting, and can operate at a maximum pressure of 5000 psi (350 bar). Leakage specifications are detailed at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Additional technical details include a pilot volume displacement of .17 in\u00b2 (8 cc), valve hex size of 1\u00bc inches (31.8 mm), and an installation torque range between 150-160 lbf\u00b7ft (203-217 Nm). The unit weighs approximately 1.80 lbs (0.80 kg). For maintenance or replacement needs, the appropriate seal kit for this cartridge is Viton: 990063006.

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.
