The Sun Hydraulics DRBBLAV (DRBBLAV) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 exceeds its setting, with pressure at port 3 being directly additive to the valve's setting. Due to this characteristic, port 3 may not be suitable as a work port in certain circuit designs; in such cases, a 4-port version of this valve might be more appropriate. The direct-acting design ensures low internal leakage and minimal pilot flow consumption, making it efficient for various applications. This model features Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. It is not bistable and can modulate between two positions as needed. The DRBBLAV fits into cavity T-11A and belongs to Series 1 with a capacity of 7 gpm (28 L/min). It is factory pressure set at 4 gpm (15 L/min) with a maximum operating pressure of up to 5000 psi (350 bar). The valve exhibits a maximum leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). Additional specifications include an adjustment requirement of approximately five clockwise turns to increase the setting, with specific torque values for installation and locknut adjustments. The model weighs .60 lb (.30 kg) and uses Viton seal kits for maintenance. This cartridge is ideal for applications requiring precise modulation and robust performance in hydraulic systems.

Normally closed, 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.
