The Sun Hydraulics DRBMKAV (DRBMKAV) is a normally open, direct-acting, 2-way directional cartridge valve designed for use in moderate flow circuits. It can be utilized independently or to activate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the preset level. This model allows port 3 to function as a work port, with a bidirectional flow path between ports 2 and 3. Thanks to its direct-acting design, this valve features low internal leakage and minimal pilot flow consumption. Direct-acting and pilot-operated versions are interchangeable, sharing the same cavities and flow paths. The DRBMKAV model incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It is capable of modulating between two positions but is not bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits, although the hydraulic operating limit is higher at a maximum operating pressure of 5000 psi (350 bar). The valve has a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). Additional specifications include a maximum valve leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt), with an adjustment capability that requires approximately five clockwise turns to increase the setting. The valve hex size measures at .78 inches (22.2 mm), with an installation torque requirement between 30-35 lbf ft (41-47 Nm). For adjustments, it features an internal hex size of .532 inches (4 mm) for the adjustment screw and a locknut hex size of .916 inches (15 mm), requiring a locknut torque of 80-90 lbf in (9-10 Nm). The model weighs .55 lb (.25 kg) and uses Viton seal kits 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.
