The Sun Hydraulics DRBBCEN (DRBBCEN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds its set threshold. It is important to note that pressure at port 3 directly adds to the valve's setting, potentially limiting its use as a work port in certain circuits. For such cases, a 4-port version of this valve might be more suitable. Featuring a direct-acting design, the DRBBCEN ensures low internal leakage and minimal pilot flow consumption. It is interchangeable with pilot-operated versions, fitting into the same cavities and maintaining identical flow paths. The valve is not bistable; it has the capability to modulate between two positions as required by system conditions. Its construction incorporates Sun's floating style design, minimizing risks of internal parts binding due to excessive installation torque or variations in cavity-cartridge machining. Key specifications include a T-11A cavity type, Series 1 classification, 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). Maximum valve leakage at 110 SUS (24 cSt) is limited to 2 in/min (30 cc/min). The adjustment mechanism allows for up to five complete clockwise turns to increase the setting. Installation requires specific torque values: valve hex size at 7/8 in. (22.2 mm), installation torque between 30 - 35 lbf ft (41 - 47 Nm), adjustment screw internal hex size at 5/32 in. (4 mm), locknut hex size at 9/16 in. (15 mm), and locknut torque ranging from 80 - 90 lbf in. (9 -10 Nm). The model weight is approximately .60 lb (.30 kg), and it comes equipped with a Viton seal kit under part number: 990011006.

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.
