The Sun Hydraulics DRBNOAN (DRBNOAN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized independently or to control larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses its set threshold. Port 3 serves as a work port, while the flow path between ports 2 and 3 is bidirectional, offering flexibility in hydraulic circuit design. Due to their direct-acting nature, these cartridges boast low internal leakage and minimal pilot flow consumption. The DRBNOAN model is interchangeable with pilot-operated versions, fitting identical cavities and maintaining consistent flow paths. Notably, pressure at port 4 directly adds to the valve's setting. This model is not bistable; it can modulate between two positions as needed. It incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. The valve features a T21A cavity with a series capacity of 7 gpm (28 L/min), factory pressure settings established at 4 gpm (15 L/min), and a maximum operating pressure of 5000 psi (350 bar). Valve leakage at 110 SUS (24 cSt) is minimal at just 2 in\u00b3/min (30 cc/min). Adjustments are made via an internal hex screw with specific torque requirements for secure installation. With its robust design and reliable performance, this cartridge valve is ideal for applications requiring precise control in hydraulic systems.

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 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.
