The Sun Hydraulics DRBBKSN (DRBBKSN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses the pre-set threshold. Notably, pressure at port 3 directly adds to the valve setting, which could limit its use as a work port in certain circuits; a four-port version may be more suitable in such cases. The direct-acting design of the DRBBKSN ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. While not bistable, this valve can modulate between two positions as needed. It incorporates Sun\u2019s floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. Key specifications include a cavity size of T-11A and a series designation of 1 with 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 is rated at 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). The adjustment mechanism allows for setting increases with up to five clockwise turns. Installation requires a torque range of 30 - 35 lbf ft (41 - 47 Nm), and the adjustment screw features an internal hex size of 5/32 inch (4 mm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for enhanced durability.

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.
