The Sun Hydraulics DRBCOBN (DRBCOBN) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This valve is particularly effective in applications where one port is blocked and another allows flow between two points. It can function independently or be used to control larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a pre-set threshold, with pressure at port 3 directly adding to this setting. Due to this characteristic, port 3 may not be suitable as a work port unless the four-port version of the valve is considered. The DRBCOBN model features low internal leakage and minimal pilot flow consumption due to its direct-acting design, and it can modulate between two positions rather than being bistable. Additionally, it incorporates Sun's floating style construction to minimize binding of internal parts from installation torque or machining variations. The valve fits into cavity T-11A and belongs to Series 1, with a capacity of handling up to 7 gallons per minute (28 liters per minute). It operates under a maximum pressure of 5000 psi (350 bar) with factory pressure settings established at a flow rate of 4 gallons per minute (15 liters per minute). It maintains low leakage rates at standard viscosity levels, with an installation torque recommendation of 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut requires a torque of 80-90 lbf in (9-10 Nm). Weighing approximately .60 lb (0.30 kg), the DRBCOBN model is compatible with Viton seal kits for effective sealing solutions.

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.
