The Sun Hydraulics DRBOCWN (Material Number: DRBOCWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or to activate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a predefined setting. Port 3 serves as a work port, with bidirectional flow paths available between ports 2 and 3, as well as ports 1 and 2. Featuring low internal leakage and minimal pilot flow consumption due to its direct-acting design, this valve is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The DRBOCWN model utilizes Sun's floating style construction, reducing the risk of internal binding from excessive installation torque or 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) because of fatigue strength limits rather than hydraulic operating limits. The valve fits into cavity T-21A, belongs to Series 1, and has a capacity of handling up to 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with the maximum operating pressure reaching up to 5000 psi (350 bar). Additional specifications include a maximum valve leakage of 2 in\u00b3/min (30 cc/min) at viscosity levels of 110 SUS (24 cSt). The adjustment screw requires five clockwise turns to increase the setting and features an internal hex size of 5/32 inches (4 mm). Installation torque for the valve ranges from 30 to 35 lbf-ft (41 to 47 Nm), while the locknut torque is set between 80 and 90 lbf-in (9 to 10 Nm). The model weighs approximately .55 lb (.25 kg) and comes with a Viton seal kit option for cartridge 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.
