The Sun Hydraulics DRBNODN (DRBNODN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. The design allows port 3 to serve as a work port with bidirectional flow between ports 2 and 3. A notable feature of this direct-acting valve is its low internal leakage and minimal pilot flow consumption, making it efficient for various applications. Its compatibility with both direct-acting and pilot-operated versions means they are interchangeable, fitting the same cavities and maintaining identical flow paths. The valve's construction incorporates Sun's floating style to prevent internal parts from binding due to excessive installation torque or machining variations in the cavity/cartridge. The DRBNODN model fits into cavity T-21A, belongs to Series 1, and has a capacity of handling up to 7 gpm (28 L/min). It is capable of operating at a maximum pressure of 5000 psi (350 bar), with factory pressure settings established at 4 gpm (15 L/min). The maximum allowable leakage at a viscosity of 110 SUS (24 cSt) is specified at 2 in\u00b3/min (30 cc/min). The valve\u2019s adjustment features include an increase setting achieved through clockwise turns, requiring specific torque values for installation and locknut adjustments. This model weighs .55 lb (.25 kg) and uses Viton seal kits for cartridge sealing.

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.
