The Sun Hydraulics DCDFXTV (DCDFXTV) is a versatile two-position, 4-way directional cartridge valve designed for high-pressure hydraulic systems. It features a spring-offset configuration and offers a choice of nine different spool options to cater to specific application needs. This model is notable for its robust construction, capable of handling pressures up to 5000 psi (350 bar) across all ports, including the pilot ports (port 5 and port 6). The valve's performance varies depending on the selected spool type, primarily due to differences in flow forces which are proportional to flow and pressure drop. The DCDFXTV valve is engineered with hardened spool and sleeve components that ensure low leakage rates and superior wear resistance. It incorporates Sun's innovative floating style construction which minimizes the risk of internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This design enhancement significantly enhances reliability and operational consistency. For applications involving phosphate ester fluids, cartridges configured with EPDM seals are recommended. However, it is crucial to avoid exposure to petroleum-based fluids as they can damage these seals. The valve's specifications also include a capacity range of 11-30 gpm (38-120 L/min), requiring a minimum pilot pressure of 150 psi (10.5 bar) to shift. Leakage specifications are detailed per path, ensuring clarity in performance expectations. Additionally, the DCDFXTV features a compact design with a model weight of approximately 0.80 lb (0.35 kg), making it suitable for various installation environments without adding significant weight or bulk. Installation requires specific torque settings between 45-50 lbf ft (61-68 Nm) and utilizes a hex size of 1 1/8 inches (28.6 mm), ensuring secure and straightforward integration into hydraulic systems.

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.
- 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.
