The Sun Hydraulics DRBBKWN (DRBBKWN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile component can function independently or serve to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the pre-set threshold, with pressure at port 3 directly affecting this setting. Due to this design characteristic, port 3 may not be viable as a work port in certain circuit applications; however, a 4-port version of the valve could address such concerns. Engineered with direct-acting technology, the DRBBKWN boasts low internal leakage and minimal pilot flow consumption. It shares cavity compatibility and flow paths with its pilot-operated counterparts, ensuring interchangeability within systems. Notably, this valve is not bistable and can modulate between two positions as needed. The incorporation of Sun's floating style construction minimizes risks of internal component binding from excessive installation torque or machining variations. Key specifications include a cavity size of T-11A, series 1 classification, and a capacity of up to 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure reaching up to 5000 psi (350 bar). Maximum valve leakage is rated at 2 in\u00b3/min (30 cc/min) at viscosity conditions of 110 SUS (24 cSt). The adjustment mechanism allows for up to five clockwise turns to increase settings, featuring an internal hex size of 5/32 inches (4 mm) for the adjustment screw. The DRBBKWN model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for durability and reliability in various applications.

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.
