The Sun Hydraulics DPBPCBN (DPBPCBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with the option to block port 4 to prevent shifting. Port 3 serves as a work port, and the valve's direct-acting and pilot-operated versions are interchangeable, fitting the same cavities and maintaining identical flow paths. The DPBPCBN incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min), this valve is capable of modulating between its two positions but is not bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. For installation, the DPBPCBN features a T21A cavity type and requires an installation torque of 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm), with a locknut torque range of 80-90 lbf in. (9-10 Nm). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), ensuring reliable performance across various applications. Additionally, this model weighs .60 lb (.30 kg) and includes a Viton seal kit for enhanced durability and sealing performance.

Pilot-operated, 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 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- 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.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- When pilot pressure exceeds the valve setting, pilot flow may be a consideration. See performance curves for pilot consumption vs. load pressure above the valve setting. If this is a problem, the direct acting version of this valve would be a solution.
- 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.
