The Sun Hydraulics DCDFXHV (DCDFXHV) is a two-position, 4-way directional cartridge valve, distinguished by its spring-offset, 6-port configuration which can be customized with one of nine different spool options. This model is engineered to accommodate a maximum operating pressure of 5000 psi (350 bar) across all ports, including both the X and Y pilot ports (port 5 and port 6). The capacity and performance of the DCDFXHV vary based on the spool type selected, primarily due to flow forces which are influenced by flow rate and pressure drop across the valve. This valve is specifically designed with hardened spool and sleeve to 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 minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Suitable for use with systems utilizing phosphate ester fluids, cartridges configured with EPDM seals should not be exposed to petroleum-based fluids as this can damage the seals. The DCDFXHV offers a flow capacity ranging from 11 to 30 gpm (38 to 120 L/min), requiring a minimum pilot pressure of 150 psi (10.5 bar) to shift the valve. It also specifies maximum leakage at a rate of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Other technical specifications include a pilot volume displacement of approximately .06 in\u00b3 (0.98 cc), a hex size for the valve at 1-1/8 inches (28.6 mm), and an installation torque requirement between 45 -50 lbf\u00b7ft (61 -68 Nm). The model weighs about .80 lb (0.35 kg), ensuring it is robust yet manageable for installation and maintenance processes.

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.
