The Sun Hydraulics DRBMKDV (DRBMKDV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile and can function independently or in conjunction with 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 set threshold. Port 3 is available for use as a work port, with bidirectional flow between ports 2 and 3. Thanks to its direct-acting design, this valve boasts low internal leakage and minimal pilot flow consumption. It shares compatibility with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The pressure at port 4 directly adds to the valve's setting, allowing modulation between two positions without being bistable. For optimal performance, maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations rather than hydraulic operating limits. The Sun floating style construction minimizes internal part binding risks from excessive installation torque or cavity-cartridge machining variations. This model fits a T21A cavity and belongs to Series 1 with a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), while the maximum operating pressure reaches up to 5000 psi (350 bar). Valve leakage is limited to a maximum of 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). Adjustment settings can be increased by turning clockwise up to five full turns. The valve features specific installation requirements: a hex size of .78 inches (22.2 mm), installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm), an adjustment screw internal hex size of .532 inches (4 mm), locknut hex size of .916 inches (15 mm), and locknut torque between 80 to 90 lbf in (9 to10 Nm). The model weighs approximately .55 lb (.25 kg) and includes a Viton seal kit under cartridge 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.
