The Sun Hydraulics DRBNODV (DRBNODV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for use in moderate flow circuits. It can be employed independently or to actuate larger pilot-operated directional or logic cartridges. This valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. Notably, port 3 can function as a work port, and the flow path between ports 2 and 3 is bidirectional. Due to its direct-acting design, this valve exhibits low internal leakage and minimal pilot flow consumption. Direct-acting and pilot-operated versions are interchangeable as they share the same cavities and flow paths. The pressure at port 4 directly adds to the valve's setting, although it is not bistable and can modulate between two positions. The maximum pressure at port 3 should be capped at 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. The Sun floating style construction minimizes internal part binding from excessive installation torque or machining variations in cavity-cartridge setups. This model fits into a T21A cavity, belongs to Series 1, with a capacity of up to 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). Valve leakage is limited to a maximum of 2 in\u00b3/min (30 cc/min) at a viscosity of 110 SUS (24 cSt). Adjustment for increasing settings involves up to five clockwise turns. The valve hex size measures .78 inches (22.2 mm), with an installation torque range of 30\u201335 lbf ft (41\u201347 Nm). The adjustment screw features an internal hex size of .156 inches (4 mm), while the locknut hex size is .5625 inches (15 mm), requiring a torque of 80\u201390 lbf in (9\u201310 Nm). The model weighs approximately .55 lb (.25 kg) and uses Viton seal kits under part number: 990021006.

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.
