The Sun Hydraulics DPBPKAN (DPBPKAN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the pre-set threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port. The DPBPKAN is interchangeable with direct-acting versions, sharing the same cavities and flow paths. It features Sun's floating style construction to mitigate internal binding due to excessive torque or machining variations. The valve is capable of modulating between two positions but is not bistable. It has a capacity of 7 gpm (28 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). For optimal performance, factory pressure settings are established at 4 gpm (15 L/min). The valve's control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum leakage at 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). Installation requires specific torque settings: the valve hex size is .78 inches (22.2 mm), installation torque ranges from 30 to 35 lbf-ft (41 to 47 Nm), and the locknut torque should be between 80 to 90 lbf-in (9 to 10 Nm). This model weighs .60 lb (.30 kg) and uses Viton seal kits for maintenance. When dealing with pilot pressure exceeding valve settings, consider potential pilot flow issues; if necessary, opt for a direct-acting version as an alternative solution.

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.
