The Sun Hydraulics DCDFXWV (DCDFXWV) is a versatile directional control valve, featuring a two-position, 4-way configuration with spring-offset and 6-port options. This pilot-to-shift valve is distinguished by its ability to handle a range of spool types, each offering different capacities and performance limits influenced by flow forces. The valve is capable of accommodating up to 5000 psi (350 bar) across all ports, including the x and y pilot ports (port 5 and port 6). The spool configurations are sensitive to flow forces which can impact the valve's shifting ability especially under high flow and pressure conditions. The DCDFXWV incorporates hardened spool and sleeve components that ensure low leakage rates and superior wear characteristics, enhancing its durability and reliability in demanding applications. It also features Sun's floating style construction which helps minimize internal binding due to installation torque or machining variations in the cavity/cartridge. Each path's leakage specifications are clearly defined in the technical data provided by Sun Hydraulics. For fluid compatibility, cartridges configured with EPDM seals are specifically designed for systems utilizing phosphate ester fluids; however, these should not be exposed to petroleum-based fluids as they can degrade the seals. The operational specifications include a capacity of 11-30 gpm (38-120 L/min), minimum pilot pressure required for valve shift at 150 psi (10.5 bar), maximum valve leakage at 110 SUS (24 cSt), and pilot volume displacement noted at .06 in\u00b3 (0.98 cc). Installation details specify a hex size of 1 1/8 in. (28.6 mm) and an installation torque between 45 - 50 lbf ft (61 - 68 Nm), with the model weighing approximately .80 lb (0.35 kg). This combination of features makes the DCDFXWV suitable for various hydraulic applications requiring precise control over fluid handling and direction within their 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.
