The Sun Hydraulics DRBBKEV (Material Number: DRBBKEV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device and 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 surpasses the predetermined setting. Notably, pressure at port 3 is directly additive to the valve's setting, which may limit its use as a work port in certain circuits; in such cases, a 4-port version might be more suitable. This direct-acting design ensures low internal leakage and minimal pilot flow consumption. Furthermore, direct-acting and pilot-operated versions are interchangeable due to their compatible cavities and flow paths. The DRBBKEV is not bistable and can modulate between two positions as shown in its configuration. It incorporates Sun's floating style construction to mitigate potential issues with internal parts binding from excessive installation torque or cavity-cartridge machining variations. Key specifications include a T11A cavity, Series 1 classification, with a capacity of handling up to 7 gpm (28 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Valve leakage at maximum conditions is limited to 2 in\u00b3/min (30 cc/min). Other features include an adjustment mechanism allowing up to five clockwise turns for increased setting, specific installation torques for the valve and locknut, and compatibility with Viton seal kits. This robust valve weighs approximately .60 lb (.30 kg), making it suitable for various hydraulic applications requiring precise control over fluid direction under high-pressure conditions.

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.
