The Sun Hydraulics DRBALSV (Material Number: DRBALSV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It 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 set threshold, with pressure at port 3 directly adding to the valve's setting. Notably, port 3 may not be suitable as a work port; if this poses an issue, a 4-port version of this valve could be considered. The direct-acting design ensures low internal leakage and minimal pilot flow consumption. Additionally, these valves are interchangeable with their pilot-operated counterparts, sharing the same cavities and flow paths. The DRBALSV is not bistable and can modulate between two positions. It incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations in cavities/cartridges. With a cavity size of T-11A and series number 1, it has a capacity of 7 gpm (28 L/min) and factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with maximum valve leakage at 2 in/min (30 cc/min). For adjustments, it requires approximately five clockwise turns to increase settings. The valve hex size measures 7/8 inch (22.2 mm), with installation torque between 30 - 35 lbf ft (41 - 47 Nm). Additional specifications include an adjustment screw internal hex size of 5/32 inch (4 mm), locknut hex size of 9/16 inch (15 mm), locknut torque ranging from 80 - 90 lbf in (9 -10 Nm), and model weight of .60 lb (.30 kg).

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.
