The Sun Hydraulics DRBDOBN (DRBDOBN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve allows flow from port 1 to port 2 while blocking port 3, making it ideal for applications requiring precise control of hydraulic fluid direction. It is particularly useful as a standalone unit or for actuating larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds its set threshold. Notably, pressure at port 3 adds directly to the valve's setting, which may limit its use as a work port in some circuits; in such cases, a 4-port version might be more suitable. Featuring low internal leakage and pilot flow consumption due to its direct-acting design, the DRBDOBN is not bistable and can modulate between two positions. The cartridge utilizes Sun's floating style construction to reduce the risk of internal component binding from excessive installation torque or machining variations. It fits into cavity T-11A, with a capacity of up to 7 gpm (28 L/min) and can withstand maximum operating pressures of up to 5000 psi (350 bar). The valve allows adjustment through clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. This model weighs approximately .60 lb (0.30 kg) and includes a Viton seal kit for enhanced durability in various operating conditions. Its compatibility with both direct-acting and pilot-operated versions ensures flexibility in application while maintaining consistent performance across different hydraulic systems.

Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
