The Sun Hydraulics DRBMKSN (DRBMKSN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be utilized to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the set value. Port 3 serves as a work port, and the flow path between ports 2 and 3 is bidirectional, making it adaptable for various hydraulic applications. Its direct-acting design ensures low internal leakage and minimal pilot flow consumption. Notably, direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The valve setting is directly influenced by pressure at port 4, allowing for modulation between positions rather than bistable operation. Maximum pressure at port 3 is capped at 3000 psi (210 bar) due to fatigue strength limits. The valve incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations in cavity-cartridge interfaces. The DRBMKSN fits cavity T-21A and belongs to Series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Valve leakage is minimal, with a maximum rate of 2 in\u00b3/min (30 cc/min) at viscosity levels of 110 SUS (24 cSt). The adjustment mechanism allows for setting increases through up to five clockwise turns. Installation requires specific torques: valve installation torque ranges from 30 to 35 lbf\u00b7ft (41 to 47 Nm), adjustment screw internal hex size is ^5/32 in. (4 mm), locknut hex size is ^9/16 in. (15 mm), and locknut torque ranges from 80 to 90 lbf\u00b7in. (9 to 10 Nm). Weighing just .55 lb (.25 kg), this cartridge comes equipped with Viton seals under part number: Viton: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.
