The Sun Hydraulics DRBNOWV (DRBNOWV) is a normally closed, direct-acting, 2-way directional cartridge valve that serves as a versatile switching device for moderate flow circuits. This valve can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a predetermined setting. Notably, port 3 can be utilized as a work port, and the flow path between ports 2 and 3 is bidirectional. Due to its direct-acting design, the valve boasts low internal leakage and minimal pilot flow consumption. Moreover, it offers interchangeability with direct-acting and pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The valve's maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of handling up to 7 gpm (28 L/min). It features Sun's floating style construction, which minimizes potential internal binding due to excessive installation torque or machining variations in the cavity/cartridge. The DRBNOWV is not bistable but can modulate between two positions as needed. The recommended maximum pressure at port 3 should not exceed 3000 psi (210 bar) to adhere to fatigue strength limits. Additional specifications include a factory pressure setting established at 4 gpm (15 L/min), maximum valve leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt), and adjustment capability via clockwise turns to increase settings up to a total of five turns. The installation requires specific torque values: valve installation torque ranges from 30\u201335 lbf\u00b7ft (41\u201347 Nm), while locknut torque should be maintained between 80\u201390 lbf\u00b7in (9\u201310 Nm). The model weighs approximately .55 lb (.25 kg) and utilizes Viton seals for optimal 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 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.
