The Sun Hydraulics DRBPXFN (DRBPXFN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a 1 to 2 open and 3 blocked configuration, making it suitable for applications requiring reliable switching devices. The valve can be used independently or to actuate larger pilot-operated directional or logic cartridges, shifting when the pressure differential between port 1 and port 4 exceeds the set threshold. The design allows for bidirectional flow between ports 2 and 3, while port 3 can also serve as a work port. With low internal leakage and pilot flow consumption, the DRBPXFN ensures efficient operation. It is interchangeable with pilot-operated versions due to its compatible cavity fitting and identical flow paths. The valve's maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of up to 7 gpm (28 L/min). It incorporates Sun's floating style construction to minimize internal part binding risks due to excessive installation torque or machining variations. The valve is not bistable but can modulate between positions based on system requirements. Maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. The DRBPXFN has a hex size of 7/8 inch (22.2 mm) and an installation torque range of 30 - 35 lbf ft (41 - 47 Nm), weighing .55 lb (.25 kg). For maintenance, a Viton seal kit is available under part number 990021006.

Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.
- Port 3 can be used as a work port.
- The flow path between port 2 and port 3 is bidirectional.
- Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- The flow path between port 1 and port 2 is bidirectional.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
