The Sun Hydraulics DRBALDV (Material Number: DRBALDV) 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 or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a predefined setting, with pressure at port 3 directly adding to this setting. Due to this characteristic, port 3 may not be suitable as a work port in certain circuits; a four-port version of the valve might be more appropriate in such cases. The direct-acting design of the DRBALDV ensures low internal leakage and minimal pilot flow consumption. These valves are interchangeable with pilot-operated versions, sharing cavity compatibility and flow paths. The DRBALDV features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. This model has a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar) and has a maximum valve leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). The adjustment screw requires five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. The cartridge fits into T-11A cavities and weighs approximately .60 lb (0.30 kg). For sealing purposes, Viton seal kits are available under part 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.
