The Sun Hydraulics DRBNLEN (Material Number: DRBNLEN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds its setting, with port 3 available as a work port. The flow path between ports 2 and 3 is bidirectional, and the direct-acting design ensures low internal leakage and minimal pilot flow consumption. Notably, direct-acting and pilot-operated versions are interchangeable due to their compatibility in cavity fittings and flow paths. The valve incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or machining variations. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits, although the maximum operating pressure is up to 5000 psi (350 bar). With a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min), this valve offers reliable performance in various applications. Additional specifications include a T21A cavity, Series 1 designation, a valve hex size of .78 inches (22.2 mm), installation torque of 30-35 lbf ft (41-47 Nm), and an adjustment screw internal hex size of .532 inches (4 mm). The locknut hex size is .916 inches (15 mm), with a torque specification of 80-90 lbf in (9-10 Nm). The model weighs .55 lb (.25 kg) and uses a Viton seal kit with part number: 990021006.

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.
