The Sun Hydraulics DRBBLWN (DRBBLWN) is a normally closed, direct-acting, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges to control hydraulic flow. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the pre-set threshold, although pressure at port 3 directly influences the valve setting. Notably, due to this pressure influence, port 3 may not be suitable as a work port within certain circuit configurations. For such scenarios, a 4-port version of this valve might be more appropriate. The DRBBLWN is characterized by its low internal leakage and minimal pilot flow consumption due to its direct-acting design. It features Sun's floating style construction which reduces the risk of internal binding from excessive installation torque or machining variations in the cavity-cartridge interface. This model is not bistable but can modulate between two positions as needed. Compatible with cavity T-11A and belonging to series 1, this cartridge has a capacity of 7 gpm (28 L/min) and operates at pressures up to 5000 psi (350 bar). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min). With maximum valve leakage rated at 2 in\u00b3/min (30 cc/min), it offers reliable performance under demanding conditions. Adjustments can be made through an internal hex screw with specific torque requirements for both installation and locknut adjustments. Weighing just .60 lb (.30 kg) and equipped with Viton seal kits, the Sun Hydraulics DRBBLWN provides robust performance for various hydraulic applications requiring precise control over fluid directionality.

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.
