The Sun Hydraulics DRBOKBV (Material Number: DRBOKBV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve is particularly useful as a switching device that can be employed independently or 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 its set threshold. It features a bidirectional flow path between ports 2 and 3, and also between ports 1 and 2, making it versatile for various hydraulic applications. Port 3 can function as a work port, with a maximum pressure limit of 3000 psi (210 bar), due to fatigue strength constraints rather than hydraulic operating limits. The DRBOKBV valve incorporates Sun\u2019s floating style construction, minimizing the risk of internal parts binding from excessive installation torque or machining variations. It fits the T-21A 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). The valve can handle a maximum operating pressure of up to 5000 psi (350 bar) and exhibits minimal leakage at around 2 in\u00b3/min (30 cc/min) when operating with oil viscosity at 110 SUS (24 cSt). For adjustments, the setting can be increased by turning clockwise up to five full turns. The valve's hex size measures at .78 inches (22.2 mm), requiring an installation torque between 30 - 35 lbf ft (41 - 47 Nm). Additionally, it comes equipped with Viton seals, ensuring durability under various operating conditions. This model weighs approximately .55 lb (.25 kg), making it lightweight yet robust for demanding applications.

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
- The flow path between port 1 and port 2 is bidirectional.
- 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.
