The Sun Hydraulics DCEFXTV (DCEFXTV) is a versatile two-position, 4-way directional cartridge valve featuring a spring-offset, 6-port configuration that allows for customization through nine different spool options. This pilot-to-shift valve ensures robust performance with all ports, including the X and Y pilot ports (port 5 and port 6), capable of handling pressures up to 5000 psi (350 bar). The valve's operational capacity varies depending on the chosen spool type, primarily due to differences in flow forces that are proportional to flow rate and pressure drop. These forces can influence the shifting behavior of the valve under certain flow and pressure conditions. The DCEFXTV model is engineered for durability and consistent performance, featuring a hardened spool and sleeve that minimize leakage and wear. It also incorporates Sun's floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. The design specifics include a T63A cavity style, belonging to Series 3, with a flow capacity range of 25 to 100 gpm (95 to 380 L/min). It requires a minimum pilot pressure of 125 psi (9 bar) to shift the valve effectively. Additional technical specifications highlight a maximum valve leakage at 110 SUS (24 cSt) of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar), with pilot volume displacement marked at .17 in\u00b2 (8 cc). For installation, the valve hex size is noted as 1\u00bc inches (31.8 mm) with an installation torque requirement between 150-160 lbf\u00b7ft (203-217 Nm). The seal kit for this model uses Viton components with part number: 990063006. This hydraulic solution is designed for systems requiring precise control over fluid direction and pressure within a wide range of applications.

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.
