The Sun Hydraulics DRBDLEN (Material Number: DRBDLEN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where ports 1 to 2 are open and port 3 is blocked, making it suitable for applications requiring switching devices. This valve can operate independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses the pre-set threshold, with the pressure at port 3 being additive to this setting. This characteristic implies that port 3 may not be usable as a work port in certain circuits; however, a four-port version of this valve could address such concerns. The DRBDLEN model employs Sun's floating style construction, minimizing the risk of internal part binding due to excessive installation torque or cavity-cartridge machining variations. It boasts low internal leakage and minimal pilot flow consumption due to its direct-acting design. The valve is capable of modulating between two positions but is not bistable. It fits into a T-11A cavity and has a capacity of handling up to 7 gpm (28 L/min) with a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), and the maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min (30 cc/min). Adjustment features include an internal hex screw for setting adjustments, with five clockwise turns required to increase settings. The installation requires specific torque values for both the valve and locknut, ensuring secure placement within hydraulic systems. The model weighs approximately .60 lb (.30 kg), and Viton seal kits are available for maintenance purposes.

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.
