The Sun Hydraulics DRBDLWN (DRBDLWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve is typically used to switch devices and can function independently or actuate larger pilot-operated directional or logic cartridges. The DRBDLWN shifts when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 directly adding to the valve setting. Due to this characteristic, port 3 may not be suitable as a work port in certain circuits; in such cases, a 4-port version might be more appropriate. The direct-acting design of this cartridge ensures low internal leakage and minimal pilot flow consumption. Notably, direct-acting and pilot-operated versions are interchangeable within the same cavity and flow paths. The DRBDLWN is not bistable and can modulate between two positions. It incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations. Key specifications include a T11A cavity, series 1 classification, a capacity of 7 gpm (28 L/min), and factory pressure settings established at 4 gpm (15 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with maximum valve leakage of 2 in\u00b3/min (30 cc/min). The adjustment requires up to five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. This model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit identified by part number 990011006.

Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
