The Sun Hydraulics DRBOLSV (DRBOLSV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its setting, with port 3 available as a work port. It features bidirectional flow paths between ports 2 and 3, as well as between ports 1 and 2. Thanks to its direct-acting design, the DRBOLSV boasts low internal leakage and minimal pilot flow consumption. Additionally, it has interchangeable direct-acting and pilot-operated versions that fit the same cavities and maintain identical flow paths. The valve incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It is capable of modulating between two positions but is not bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar), considering fatigue strength limits rather than hydraulic operating limits. Key specifications include a T21A cavity, series 1 capacity of up to 7 gpm (28 L/min), and a factory pressure setting established at 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar), with a maximum valve leakage at 110 SUS (24 cSt) of only 2 in\u00b3/min (30 cc/min). For adjustment, there are approximately five turns needed clockwise to increase the setting. The valve's hex size is .78 inches (22.2 mm), with an installation torque range of 30 - 35 lbf ft (41 - 47 Nm). The model weighs .55 lb (.25 kg) and includes a Viton seal kit option for enhanced durability in various applications.

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.
