The Sun Hydraulics DRBNLEV (DRBNLEV) 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 the set threshold. The valve features a bidirectional flow path between port 2 and port 3, with port 3 also serving as a work port. Notably, this valve offers low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with both direct-acting and pilot-operated valves, fitting the same cavities and maintaining identical flow paths. The DRBNLEV is capable of modulating between its two positions but is not bistable. Its maximum pressure at port 3 should remain within 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating constraints. The valve incorporates Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or machining variations in the cavity or cartridge. The DRBNLEV fits into a T21A cavity and belongs to Series 1, offering a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at a flow of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Maximum leakage is limited to 2 in\u00b3/min (30 cc/min) at a viscosity of 110 SUS (24 cSt). For adjustments, an increase in setting requires approximately five clockwise turns. Installation specifications include a valve hex size of .78 inches (22.2 mm), an installation torque range of 30\u201335 lbf ft (41\u201347 Nm), an adjustment screw internal hex size of .156 inches (4 mm), and locknut torque between 80\u201390 lbf in (9\u201310 Nm). The model weighs approximately .55 lb (.25 kg) and utilizes Viton seal kits for cartridge 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.
