The Sun Hydraulics DRBDCSN (DRBDCSN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It features a configuration where ports 1 and 2 are open, and port 3 is blocked, making it suitable for applications requiring precise control over fluid direction. This valve operates by shifting when the pressure differential between port 1 and port 3 exceeds the set threshold. Notably, pressure at port 3 adds directly to the valve's setting, which may limit its use as a work port in certain circuits; in such cases, a 4-port version might be more appropriate. The DRBDCSN's direct-acting design offers low internal leakage and minimal pilot flow consumption, enhancing efficiency in hydraulic systems. It is compatible for interchange with pilot-operated versions due to its consistent cavity fit (T-11A) and identical flow paths. Despite not being bistable, this valve can modulate between its two positions effectively. Constructed with Sun\u2019s floating style design, the DRBDCSN minimizes binding risks from excessive installation torque or machining variations. The valve supports a capacity of 7 gpm (28 L/min) and operates at a maximum pressure of 5000 psi (350 bar). With factory pressure settings established at 4 gpm (15 L/min), it ensures reliable performance under various conditions. Additional specifications include a maximum leakage rate of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt), adjustment capability through clockwise turns to increase settings up to five full rotations, and specific installation torques for both the valve body and locknut. The model weighs .60 lb (.30 kg) and utilizes Viton seals 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.
