The Sun Hydraulics DRBDLDN (DRBDLDN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits, allowing for efficient switching between ports. This model features a flow path that is 1 to 2 open and 3 blocked, making it suitable for use either independently or to actuate 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 set threshold, with pressure at port 3 being directly additive to the valve's setting. This characteristic may limit the usability of port 3 as a work port in certain circuits; in such cases, considering a 4-port version might be more appropriate. The DRBDLDN cartridge boasts low internal leakage and minimal pilot flow consumption due to its direct-acting design. It also offers interchangeability with pilot-operated versions, fitting identical cavities and maintaining consistent flow paths. However, this valve is not bistable and can modulate between two positions as needed. The construction incorporates Sun's floating style to reduce the risk of internal parts binding caused by excessive installation torque or machining variations. Key specifications include a cavity size of T-11A, series number 1, with a capacity of handling up to 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in/min (30 cc/min). The adjustment involves up to five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments provided. The model weighs .60 lb (.30 kg) and uses Viton seal kits for optimal performance.

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.
