The Sun Hydraulics DCFFXTV (DCFFXTV) is a two-position, 4-way directional cartridge valve that features a spring-offset, 6-port design configurable with nine different spool options. This versatile valve is engineered for high-performance applications with all ports, including the X and Y pilot ports (port 5 and port 6), capable of handling pressures up to 5000 psi (350 bar). The flow capacity of the DCFFXTV varies depending on the spool type chosen, which affects the flow forces\u2014forces proportional to flow and pressure drop that can resist passage opening. Specifically designed to offer reliability in various hydraulic systems, the DCFFXTV incorporates hardened spool and sleeve components that ensure low leakage rates and superior wear characteristics. This model also benefits from Sun's floating style construction, which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. The valve features a T64A cavity, belongs to Series 4, and supports a flow capacity ranging from 50 to 200 gpm (200 to 760 L/min). It requires a minimum pilot pressure of 125 psi (9 bar) to shift and has a maximum leakage rate at 110 SUS (24 cSt) of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Additionally, the DCFFXTV has pilot volume displacement of .42 in\u00b3 (6.9 cc), uses a valve hex size of 1-5/8 inches (41.3 mm), and requires an installation torque between 350 -375 lbf\u00b7ft (474 -508 Nm). The model weighs approximately 3.90 lb (1.75 kg), and utilizes Viton seals for enhanced performance durability under various operating conditions.

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.
- 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.
