The Sun Hydraulics DRBALDN (Material Number: DRBALDN) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold. Notably, pressure at port 3 directly adds to the valve's setting, which may limit its use as a work port in certain circuits; in such cases, a 4-port version might be more suitable. The direct-acting design ensures low internal leakage and minimal pilot flow consumption. These cartridges are interchangeable with pilot-operated versions, fitting the same cavities and maintaining identical flow paths. The valve is not bistable but can modulate between two positions due to its construction that minimizes internal binding from excessive torque or machining variations. The DRBALDN 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). Leakage is limited to a maximum of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustment for increasing the setting requires approximately five clockwise turns. The hex size for installation is 7/8 inch (22.2 mm), with an installation torque of 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw uses an internal hex size of 5/32 inch (4 mm), while the locknut has a hex size of 9/16 inch (15 mm) and requires torque of 80 - 90 lbf in (9 -10 Nm). Weighing .60 lb (.30 kg), it features Viton seals available under seal kit number: 990011006.

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.
