The Sun Hydraulics DRBNKSN (Material Number: DRBNKSN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or serve to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a preset value. Port 3 is available for use as a work port, with bidirectional flow possible between ports 2 and 3. Thanks to its direct-acting design, the valve boasts low internal leakage and minimal pilot flow consumption. Direct-acting and pilot-operated versions are interchangeable in terms of cavity fit and flow paths. This model features Sun's floating-style construction to reduce internal binding risks due to excessive installation torque or machining variations. It has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The valve is not bistable but can modulate between two positions, with pressure at port 4 directly adding to the valve setting. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. Additional specifications include a valve hex size of 7/8 inch (22.2 mm), installation torque range of 30\u201335 lbf ft (41\u201347 Nm), an adjustment screw internal hex size of 5/32 inch (4 mm), locknut hex size of 9/16 inch (15 mm), and locknut torque range of 80\u201390 lbf in (9\u201310 Nm). The model weighs .55 lb (.25 kg) and uses Viton seal kits 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.
