The Sun Hydraulics DRBMKAN (DRBMKAN) is a normally open, direct-acting, 2-way directional cartridge designed for moderate flow circuits. It functions as a switching device and can be employed independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the preset level. Port 3 serves as a work port, with bidirectional flow capability between ports 2 and 3. This direct-acting design ensures low internal leakage and minimal pilot flow consumption. The DRBMKAN model is interchangeable with both direct-acting and pilot-operated versions, fitting the same cavities and maintaining identical flow paths. Pressure at port 4 adds directly to the valve's setting, which is not bistable but modulates between two positions. Maximum pressure at port 3 is recommended to remain below 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. Incorporating Sun's floating style construction minimizes risks of internal parts binding from excessive installation torque or cavity-cartridge machining variations. It fits a T21A cavity in Series 1 with a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar), with valve leakage capped at 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). Adjustments require up to five clockwise turns for increasing settings, using an internal hex size of 5/32 inch (4 mm) for the screw, while installation demands torque of 30-35 lbf-ft (41-47 Nm). The locknut requires a hex size of 9/16 inch (15 mm) with torque specifications between 80-90 lbf-in (9-10 Nm). The model weighs approximately .55 lb (.25 kg), with Viton seal kits available under part number 990021006.

Normally open, direct-acting, 2-way directional cartridges 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.
- 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.
