The Sun Hydraulics DRBNKWN (DRBNKWN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can operate independently or be used to actuate larger pilot-operated or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 surpasses the set threshold. Port 3 serves as a work port, with a bidirectional flow path between ports 2 and 3. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient and reliable. Additionally, these cartridges are interchangeable with pilot-operated versions, fitting the same cavities and providing similar flow paths. The DRBNKWN features Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge interface. It is capable of modulating between two positions but is not bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic operating limits. The valve has a cavity size of T-21A, belongs to series 1, and has a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Maximum valve leakage at viscosity levels of 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min). Adjustments can be made using an internal hex screw with clockwise turns increasing the setting; it requires specific torque values for installation and locknut adjustments. Weighing .55 lb (.25 kg), this model includes Viton seal kits for enhanced durability in various applications.

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.
