The Sun Hydraulics DRBBOSV (DRBBOSV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or serve as an actuator for larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses a predefined setting, with pressure at port 3 directly affecting the valve's setting. Due to this characteristic, port 3 may not be suitable as a work port in certain circuit designs, but a four-port variant of this valve is available to address such concerns. Featuring low internal leakage and minimal pilot flow consumption due to its direct-acting design, the DRBBOSV is interchangeable with pilot-operated versions, sharing cavity compatibility and flow paths. It is not bistable but can modulate between two positions as needed. The valve incorporates Sun's floating style construction to reduce the risk of internal part binding from excessive installation torque or machining variations. Key specifications include a T-11A cavity, Series 1 classification, and a capacity of 7 gpm (28 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). The adjustment mechanism allows for up to five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. The model has a weight of .60 lb (.30 kg) and utilizes Viton seal kits for optimal performance.

Normally closed, 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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- 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.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
