The Sun Hydraulics DRBALEV (Material Number: DRBALEV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used 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 its set value, with pressure at port 3 directly adding to the setting. This design consideration means port 3 may not be suitable as a work port in some circuits; in such cases, a 4-port version of this valve could be an alternative. The direct-acting design ensures low internal leakage and minimal pilot flow consumption. These valves are interchangeable with their pilot-operated counterparts, sharing the same cavities and flow paths. Notably, this valve is not bistable and can modulate between two positions as needed. The cartridge incorporates Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or machining variations in cavity-cartridge interfaces. It fits into a T-11A cavity and belongs to Series 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 at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). Adjusting the setting requires up to five clockwise turns, with specific torque values provided for installation and locknut adjustments. The model weighs .60 lb (.30 kg) and uses Viton seal kits for optimal 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.
