The Sun Hydraulics DRBPCDN (DRBPCDN) is a direct-acting, 3-way directional cartridge valve designed for use in moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds the set value, allowing for bidirectional flow between ports 1 and 2, as well as ports 2 and 3. Port 3 may also be utilized as a work port, with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength considerations. This model features low internal leakage and pilot flow consumption due to its direct-acting design and is interchangeable with pilot-operated versions, sharing the same cavities and flow paths. With a capacity of 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), it incorporates Sun's floating style construction to minimize internal binding risks during installation or due to machining variations. The valve's factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with an adjustment range that can be increased through up to five clockwise turns. The DRBPCDN valve is not bistable but capable of modulating between two positions, making it highly adaptable for various circuit applications requiring precise control. Installation specifications include a valve hex size of 7/8 in. (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). The model weighs .55 lb (.25 kg) and utilizes a Viton seal kit for reliable performance under demanding 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 4 exceeds the setting.
- Port 3 can be used as a work port.
- The flow path between port 2 and port 3 is bidirectional.
- 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.
- Pressure at port 4 is directly additive to the setting of the valve.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- The flow path between port 1 and port 2 is bidirectional.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
