The Sun Hydraulics DRBALAV (Material Number: DRBALAV) is a normally open, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. It is primarily used as a switching device and can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the preset threshold, with pressure at port 3 being directly additive to the setting. Due to this characteristic, port 3 might not be suitable as a work port in some circuits, suggesting that the 4-port version could be an alternative solution. This direct-acting design ensures low internal leakage and minimal pilot flow consumption. The DRBALAV model is not bistable, allowing it to modulate between two positions and incorporates Sun's floating style construction to reduce the risk of internal parts binding from excessive installation torque or cavity-cartridge machining variations. It fits within 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 has a maximum leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Adjustments are made through clockwise turns, with specific hex sizes provided for the adjustment screw and locknut. Installation requires specific torque values for optimal performance. The model weighs approximately .60 lb (.30 kg) and uses Viton seals, making it robust and stable for various applications requiring precise directional control.

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.
