The Sun Hydraulics DCFCXXV (DCFCXXV) is a three-position, 4-way directional cartridge valve that is spring-centered and features a 6-port directional control. This model is specifically designed to handle high-pressure applications up to 5000 psi (350 bar), making it suitable for various hydraulic systems where precise flow control is required. The valve's capacity varies depending on the spool type specified, with options available to suit different flow and pressure conditions. A key feature of the DCFCXXV is its robust construction, including a hardened spool and sleeve which ensure low leakage rates and excellent wear characteristics. This durability is complemented by Sun\u2019s floating style construction that minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The valve offers a flow capacity range of 50 to 200 gallons per minute (200 to 760 liters per minute), and requires a minimum pilot pressure of 125 psi (9 bar) for shifting. It also incorporates positively sealed pilot ports (ports 5 and 6) from the work ports, enhancing its performance reliability. For environments using phosphate ester fluids, cartridges configured with EPDM seals are available, although these are not suitable for contact with petroleum-based fluids. Other technical specifications include a maximum valve leakage at 110 SUS (24 cSt) of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar), pilot volume displacement of approximately .42 in\u00b3 (6.9 cc), and an installation torque requirement between 350 \u2013375 lbf\u00b7ft (474 \u2013508 Nm). The model weighs about 3.80 lbs (1.75 kg) and can be equipped with either Viton or EPDM seals depending on the application needs.

Three-position, 4-way directional cartridges are spring-centered, 6-port directional valves that can be configured from a choice of 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.
