The Sun Hydraulics DRBOCEN (Material Number: DRBOCEN) is a direct-acting, 3-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 set threshold. The valve features a bidirectional flow path between ports 2 and 3, with port 3 also serving as a work port. Its direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it an efficient choice for hydraulic systems. The DRBOCEN is interchangeable with pilot-operated versions, fitting the same cavities and maintaining consistent flow paths. Pressure at port 4 adds directly to the valve's setting, allowing for modulation between two positions rather than bistable operation. The maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. The Sun floating style construction minimizes the risk of internal part binding from excessive installation torque or cavity/cartridge machining variations. Additional specifications include a T-21A cavity, Series 1 designation, and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The valve allows for adjustment through clockwise turns to increase settings up to a maximum leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). It features specific installation torque requirements and hex sizes for the valve body and adjustment components. The model weighs .55 lb (.25 kg) and includes a Viton seal kit option.

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.
