The Sun Hydraulics DRBNLBN (DRBNLBN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in application, functioning independently or as an actuator for larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds the preset threshold. Port 3 can serve as a work port, with bidirectional flow capability between ports 2 and 3. This direct-acting design ensures low internal leakage and minimal pilot flow consumption. Notably, direct-acting and pilot-operated versions of this valve are interchangeable due to their compatible cavities and flow paths. The valve's setting is directly influenced by the pressure at port 4, allowing modulation between two positions without bistability. To maintain structural integrity, maximum pressure at port 3 should not surpass 3000 psi (210 bar). The Sun floating style construction minimizes internal binding risks caused by excessive installation torque or machining variations. This cartridge fits into a T-21A cavity and 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 an oil viscosity of 110 SUS (24 cSt). Adjustment involves up to five clockwise turns to increase the setting, utilizing an internal hex size of 5/32 inches (4 mm) for the adjustment screw and a locknut hex size of 9/16 inches (15 mm). The installation torque ranges from 30 to 35 lbf-ft (41 to 47 Nm), while locknut torque ranges from 80 to 90 lbf-in (9 to10 Nm). With a model weight of .55 lb (.25 kg), this valve includes Viton seal kits for optimal performance in hydraulic systems.

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.
