The Sun Hydraulics DRBALBN (DRBALBN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It operates by shifting when the pressure differential between port 1 and port 3 exceeds the preset value, with pressure at port 3 directly affecting the setting. This feature may limit its use as a work port in some circuits, but a 4-port version is available for such applications. The valve boasts low internal leakage and pilot flow consumption due to its direct-acting design. It is capable of modulating between two positions and is not bistable. The DRBALBN incorporates Sun's floating style construction to minimize potential binding of internal parts from excessive installation torque or machining variations. It fits into cavity T-11A 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 valve allows adjustment through clockwise turns to increase the setting, featuring an adjustment screw internal hex size of 5/32 in. (4 mm) and a locknut hex size of 9/16 in. (15 mm). Installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), while locknut torque ranges from 80 to 90 lbf in. (9 to 10 Nm). The model weighs .60 lb (.30 kg) and uses Viton seal kits for maintenance.

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.
