The Sun Hydraulics DRBAKWN (DRBAKWN) is a normally open, 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 exceeds the preset value, with pressure at port 3 being directly additive to the 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 be an alternative solution if needed. The DRBAKWN is characterized by low internal leakage and minimal pilot flow consumption due to its direct-acting design. It is interchangeable with pilot-operated versions, sharing the same cavities and flow paths, but it is not bistable, allowing for modulation between two positions. The valve incorporates Sun's floating style construction to reduce the risk of internal part binding from excessive installation torque or machining variations. Key specifications include a T-11A cavity size, 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 maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min). Adjustment involves up to five 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 between 80 - 90 lbf in. (9 -10 Nm). The model weighs .60 lb (.30 kg) and features Viton seal kits for reliable sealing performance.

Normally open, 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.
