The Sun Hydraulics DRBNKDV (Material Number: DRBNKDV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used 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 the preset threshold, with port 3 available as a work port. Featuring bidirectional flow between ports 2 and 3, this valve is known for its low internal leakage and minimal pilot flow consumption due to its direct-acting design. The DRBNKDV model incorporates Sun's floating style construction, reducing the risk of internal parts binding from excessive installation torque or machining variations. It is interchangeable with other direct-acting and pilot-operated versions, fitting the same cavities and offering identical flow paths. The maximum operating pressure is rated at 5000 psi (350 bar), while maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength considerations. With a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min), this model provides stable performance in various applications. The valve features a hex size of 7/8 in. (22.2 mm) for installation torque between 30-35 lbf ft (41-47 Nm). Additional specifications include an adjustment screw internal hex size of 5/32 in. (4 mm), locknut hex size of 9/16 in. (15 mm), and a locknut torque range of 80-90 lbf in. (9-10 Nm). The DRBNKDV weighs approximately .55 lb (.25 kg) and includes a Viton seal kit for enhanced durability under different operating conditions.

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.
