The Sun Hydraulics DRBBCWN (Material Number: DRBBCWN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 being directly additive to this setting. This feature may limit the usability of port 3 as a work port in certain circuits; however, a 4-port version of this valve could address such concerns. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. These cartridges are interchangeable with pilot-operated versions, sharing the same cavities and flow paths. Notably, the valve is not bistable and can modulate between two positions as required. Incorporating Sun's floating style construction minimizes potential binding of internal parts due to excessive installation torque or machining variations in cavity-cartridge interfaces. The DRBBCWN fits into a T-11A cavity and belongs to Series 1 with 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), withstanding a maximum operating pressure of up to 5000 psi (350 bar). The valve exhibits maximum leakage of only 2 in/min (30 cc/min) at an oil viscosity of 110 SUS (24 cSt). Adjustments to increase the setting can be made with up to five clockwise turns. Installation requires specific torque values for both the valve itself and its locknut, ensuring secure placement within hydraulic systems.

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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- 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.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
