The Sun Hydraulics DCDFXXV (DCDFXXV) is a versatile and robust two-position, 4-way directional cartridge valve, suitable for a range of hydraulic applications. This spring-offset, 6-port directional valve is engineered to handle pressures up to 5000 psi (350 bar) across all ports, including the pilot ports (port 5 and port 6). The DCDFXXV can be tailored to specific system needs through a selection of nine different spool options, each affecting the valve's flow force characteristics and operational capacities. These flow forces are crucial as they influence the resistance against passage openings during operation. Optimized for reliability and performance, the DCDFXXV features hardened spool and sleeve components that ensure low leakage rates and superior wear characteristics. This model also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding\u2014a common issue arising from excessive installation torque or variations in cavity/cartridge machining. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based fluids, greases, and lubricants. The valve's technical specifications include a capacity ranging from 11 to 30 gpm (38 to 120 L/min), with a minimum pilot pressure requirement of 150 psi (10.5 bar) for valve shifting. The maximum leakage at operational conditions is specified at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Additionally, this model offers ease of installation with a specified hex size of 1-1/8 in (28.6 mm) and an installation torque range between 45 -50 lbf-ft (61 -68 Nm), weighing approximately .80 lb (0.35 kg).

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.
