The Sun Hydraulics DRBMKBV (DRBMKBV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can operate independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. This valve shifts when the pressure differential between port 1 and port 4 exceeds its set value, with port 3 available as a work port. The bidirectional flow path between port 2 and port 3 enhances its versatility in various applications. Due to its direct-acting design, the DRBMKBV features low internal leakage and minimal pilot flow consumption. Both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and maintaining identical flow paths. The pressure at port 4 directly adds to the valve's setting, allowing fine-tuned control. This model is not bistable; it can modulate between two positions based on circuit demands. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic operating limits. The valve utilizes Sun's floating-style construction, reducing the risk of internal parts binding from excessive installation torque or machining variations in cavity/cartridge interfaces. The DRBMKBV 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), with a maximum operating pressure of 5000 psi (350 bar). Maximum valve leakage is limited to 2 in\u00b3/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). Adjustments can be made with up to five clockwise turns, using an internal hex size adjustment screw measuring 5/32 in. (4 mm). The model weighs .55 lb (.25 kg) and comes with a Viton seal kit for maintenance needs.

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.
