The Sun Hydraulics DRBNKBN (DRBNKBN) 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 set threshold. Port 3 serves as a work port, supporting bidirectional flow between ports 2 and 3. Thanks to its direct-acting design, this cartridge ensures low internal leakage and minimal pilot flow consumption. It is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The DRBNKBN model features a cavity size of T21A and belongs to Series 1 with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). It can withstand a maximum operating pressure of up to 5000 psi (350 bar), while the maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). The valve's adjustment mechanism allows for precision with up to 5.5 clockwise turns needed to increase settings. Additional specifications include a valve hex size of 7/8 inch (22.2 mm) and an installation torque range between 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut requires a hex size of 9/16 inch (15 mm) torqued at 80 -90 lbf in. (9 -10 Nm). Weighing approximately .55 lb (.25 kg), this model incorporates Sun Hydraulics' floating style construction to reduce potential binding issues from excessive torque or machining variations.

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.
