The Sun Hydraulics DRBMKBN (DRBMKBN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate larger pilot-operated directional or logic cartridges. This valve shifts when the pressure differential between port 1 and port 4 exceeds the set threshold, with port 3 available as a work port and bidirectional flow possible between ports 2 and 3. The direct-acting design ensures low internal leakage and minimal pilot flow consumption. This model is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The pressure at port 4 directly affects the valve setting, while maximum pressure at port 3 should not exceed 3000 psi due to fatigue strength limits. The Sun floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations. Key specifications include a T21A cavity, series 1 designation, a capacity of 7 gpm (28 L/min), factory pressure settings established at 4 gpm (15 L/min), and a maximum operating pressure of 5000 psi (350 bar). Maximum valve leakage is limited to 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). The adjustment for increasing settings requires approximately five full clockwise turns, with installation torque specified between 30-35 lbf ft (41-47 Nm). Additional features include an adjustment screw internal hex size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), with locknut torque ranging from 80-90 lbf in (9-10 Nm). The model weighs .55 lb (.25 kg) and utilizes a Viton seal kit 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.
