The Sun Hydraulics DPCPKBN (DPCPKBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It is typically utilized as a switching device that can operate independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds its setting, with port 4 capable of being blocked to prevent shifting. Port 3 may serve as a work port, though maximum pressure at this port should be limited to 3000 psi due to fatigue strength limits. This valve is not bistable and can modulate between two positions, featuring interchangeable direct-acting and pilot-operated versions that fit the same cavities and have identical flow paths. The DPCPKBN incorporates Sun's floating style construction, minimizing internal binding risks due to excessive installation torque or machining variations. It fits into cavity T-22A, belonging to series 2 with a capacity of 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), while maximum valve leakage at 110 SUS (24 cSt) is rated at 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). Adjustment involves up to five clockwise turns to increase the setting, with specific torque requirements for both installation and locknut adjustments. This cartridge weighs approximately .60 lb (0.30 kg) and uses Viton seals available under part number 990022006. The design allows for modulation rather than bistability, making it suitable for applications requiring precise control over fluid direction in hydraulic systems.

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.
