The Sun Hydraulics DRBDCDN (DRBDCDN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve functions by opening from port 1 to port 2 while blocking port 3, and it shifts when the pressure differential between port 1 and port 3 surpasses the preset value. Notably, pressure at port 3 adds directly to the valve's setting, limiting its use as a work port unless a 4-port version is employed. The direct-acting design of this cartridge ensures low internal leakage and minimal pilot flow consumption, making it efficient and reliable. This model is capable of modulating between two positions rather than being bistable, offering precision in control applications. The DRBDCDN incorporates Sun's floating style construction to reduce the risk of internal part binding due to excessive installation torque or machining variations. It fits into a T-11A cavity and belongs to Series 1 with a capacity of up to 7 gpm (28 L/min). The factory pressure setting is established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure capability of up to 5000 psi (350 bar). The valve features an installation torque requirement of 30-35 lbf ft (41-47 Nm), and adjustments can be made using an internal hex screw with specified torque settings for secure operation. For maintenance or replacement purposes, it utilizes Viton seal kits. Overall, the Sun Hydraulics DRBDCDN valve offers robust performance in hydraulic systems requiring precise modulation and control under varying pressure conditions.

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.
