The Sun Hydraulics DRBCCWN (Material Number: DRBCCWN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device with 1 port blocked and allows flow between ports 2 and 3 when the pressure differential between port 1 and port 3 exceeds the preset value. This valve is particularly suitable for applications requiring low internal leakage and minimal pilot flow consumption. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), it provides reliable modulation between positions rather than bistable operation. The DRBCCWN features Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or cavity-cartridge machining variations. It fits into cavity T-11A and is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. The valve's factory pressure settings are established at a flow rate of 4 gpm (15 L/min), ensuring optimal performance in various hydraulic circuits. The adjustment mechanism involves up to 5.5 clockwise turns to increase the setting, with an adjustment screw internal hex size of 5/32 inches (4 mm). The valve hex size is 7/8 inches (22.2 mm), requiring an installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm). For secure adjustments, the locknut hex size is set at 9/16 inches (15 mm) with a locknut torque specification of 80 to 90 lbf in (9 to 10 Nm). The DRBCCWN weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for enhanced durability in demanding environments.

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
