The Sun Hydraulics DRBDLEV (DRBDLEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve features a configuration where ports 1 and 2 are open, and port 3 is blocked. It can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds the set value, with pressure at port 3 being directly additive to the setting. Due to this characteristic, port 3 may not be suitable as a work port in some circuits, and a four-port version might be necessary for such applications. The DRBDLEV valve boasts low internal leakage and minimal pilot flow consumption thanks to its direct-acting design. It's interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The valve is not bistable; instead, it modulates between two positions as needed. It incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. Key specifications include a T-11A cavity, Series 1 classification, a capacity of up to 7 gpm (28 L/min), and 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), with maximum valve leakage rated at 2 in\u00b3/min (30 cc/min). The adjustment requires up to five clockwise turns to increase the setting, with specific torque values provided for installation and locknut adjustments. This model weighs approximately .60 lb (0.30 kg) and uses Viton seals for reliable performance in hydraulic systems.

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.
