The Sun Hydraulics DRBNCDN (Material Number: DRBNCDN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can operate independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. This 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. Both direct-acting and pilot-operated versions are interchangeable, fitting the same cavities with identical flow paths. The valve's pressure at port 4 is directly additive to its setting, although it is not bistable and can modulate between two positions. Maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. The Sun floating style construction minimizes potential internal part binding caused by excessive installation torque or cavity-cartridge machining variations. Key specifications include a T21A cavity, Series 1 capacity of 7 gpm (28 L/min), factory pressure settings established at 4 gpm (15 L/min), and a maximum operating pressure of 5000 psi (350 bar). The valve\u2019s maximum leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min). Adjustment involves up to five clockwise turns to increase settings, utilizing an adjustment screw with an internal hex size of 5/32 inch (4 mm). Installation requires a torque of 30-35 lbf\u00b7ft (41-47 Nm), while the locknut requires a torque of 80-90 lbf\u00b7in (9-10 Nm). The model weighs .55 lb (.25 kg) and uses Viton seal kit number: 990021006 for maintenance.

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.
