The Sun Hydraulics DRBALSN (DRBALSN) is a normally open, direct-acting, 2-way directional cartridge valve that excels in moderate flow circuits. This versatile component can function independently or serve as an actuator for larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses its set threshold. It's important to note that pressure at port 3 directly adds to the valve's setting, potentially limiting its use as a work port in certain circuits; in such cases, a 4-port version might be more suitable. Thanks to its direct-acting design, the DRBALSN features minimal internal leakage and low pilot flow consumption. It is interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. Although not bistable, this valve can modulate between two positions seamlessly. Its construction incorporates Sun's floating style design to reduce risks of internal part binding due to excessive torque or machining variations. The DRBALSN fits into a T-11A cavity and belongs to Series 1 with a capacity of 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). The valve exhibits maximum leakage of 2 in/min (30 cc/min) at viscosity levels of 110 SUS (24 cSt). Adjustment is achieved through clockwise turns with specific torque requirements for installation and locknut adjustments. Weighing .60 lb (.30 kg), it comes equipped with Viton seal kits for enhanced durability and performance under various conditions.

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.
