The Sun Hydraulics DRBPKEV (Material Number: DRBPKEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device primarily used to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses the set value, with port 3 serving as a work port. It features bidirectional flow paths between ports 2 and 3, as well as ports 1 and 2, offering versatility in hydraulic systems. Due to its direct-acting design, the DRBPKEV provides low internal leakage and minimal pilot flow consumption. This cartridge is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The valve incorporates Sun's floating style construction to reduce the risk of internal parts binding due to installation torque or machining variations. It is capable of modulating between two positions but is not bistable. The maximum operating pressure reaches up to 5000 psi (350 bar), with a capacity of handling flows up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The valve's hex size measures 7/8 inches (22.2 mm), requiring an installation torque between 30 - 35 lbf ft (41 - 47 Nm). For adjustments, it features an internal hex size of 5/32 inches (4 mm) for the adjustment screw and a locknut hex size of 9/16 inches (15 mm), with locknut torque ranging from 80 - 90 lbf in (9 -10 Nm). The maximum allowable leakage at viscosity levels of 110 SUS (24 cSt) is limited to 2 in\u00b3/minute (30 cc/minute). The product weighs approximately .55 lb (.25 kg) and uses Viton seal kits for maintenance or replacement needs.

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.
