The Sun Hydraulics DRBBOBN (DRBBOBN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can operate independently or be used to actuate larger pilot-operated directional or logic cartridges. It shifts when the pressure differential between port 1 and port 3 exceeds the preset value, with pressure at port 3 directly adding to the valve's setting. Due to this characteristic, port 3 might not be suitable as a work port in certain circuits; in such cases, a four-port version could be considered. The direct-acting design ensures low internal leakage and minimal pilot flow consumption. These cartridges are interchangeable with pilot-operated versions, offering identical cavity fits and flow paths. The DRBBOBN model features Sun's floating style construction, which minimizes internal parts binding due to excessive installation torque or machining variations. It has a capacity of 7 GPM (28 L/min) and can operate under pressures up to 5000 psi (350 bar). Factory pressure settings are established at 4 GPM (15 L/min), and the maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). For adjustments, the valve requires approximately five turns clockwise to increase settings. The hex size for installation is 7/8 inch (22.2 mm), with an installation torque of 30-35 lbf\u00b7ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm) with a torque requirement of 80-90 lbf\u00b7in (9-10 Nm). The model weighs .60 lb (.30 kg) and uses Viton seal kits for enhanced durability and 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.
