The Sun Hydraulics DRBNKWV (DRBNKWV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the specified setting. Notably, port 3 can serve 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 for various applications. Direct-acting and pilot-operated versions are interchangeable as they fit the same cavities and share identical flow paths. The DRBNKWV 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. It has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min). Maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min), ensuring efficient operation. For installation, the valve requires a torque of 30 - 35 lbf ft (41 - 47 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm). The locknut has a hex size of 9/16 in. (15 mm) and requires a torque of 80 - 90 lbf in. (9 -10 Nm). Weighing .55 lb (.25 kg), this model is compact yet robust, suitable for various hydraulic systems where reliable switching is essential.

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.
