The Sun Hydraulics DRBOLEV (Material Number: DRBOLEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device with one port blocked and allows bidirectional flow between ports 2 and 3. This valve can be used independently or 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 preset value, with pressure at port 4 being directly additive to the valve setting. The DRBOLEV features low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, fitting the same cavities and maintaining consistent flow paths. The valve's maximum operating capacity is 7 gpm (28 L/min), with a factory pressure setting established at 4 gpm (15 L/min). It can withstand a maximum operating pressure of up to 5000 psi (350 bar), while the maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. The DRBOLEV incorporates Sun's floating style construction, reducing the likelihood of internal part binding from excessive installation torque or machining variations. Additional specifications include a cavity size of T-21A, series number of 1, and a valve hex size of .78 inches (22.2 mm). The adjustment screw has an internal hex size of .532 inches (4 mm) with a locknut hex size of .916 inches (15 mm). Installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), while locknut torque is between 80 to 90 lbf in (9 to 10 Nm). The model weighs approximately .55 lb (.25 kg) and uses Viton seal kits for maintenance.

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
- The flow path between port 1 and port 2 is bidirectional.
- 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.
