The Sun Hydraulics DPBOKAV (DPBOKAV) is a pilot-operated, 3-way directional cartridge valve designed for use in moderate flow circuits. This versatile valve can be employed independently or to actuate larger pilot-operated directional cartridges or logic cartridges. It functions by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 4 capable of being blocked to prevent shifting. Port 3 serves as a work port, and the valve is interchangeable with direct-acting versions, sharing the same cavities and flow paths. The valve's maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of handling up to 7 gpm (28 L/min). The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. The DPBOKAV model incorporates Sun's floating style construction, minimizing internal part binding risks from excessive installation torque or cavity/cartridge machining variations. It features an adjustment mechanism that allows for increasing settings through a number of clockwise turns, providing flexibility in operation. The valve's design ensures minimal leakage, with a maximum leakage rate of 1 in\u00b3/min at 110 SUS (24 cSt) under a pressure of 1000 psi (70 bar). Its compact form factor includes specific dimensions for installation torque and hex sizes for both the valve and locknut adjustments. Additionally, it offers a control pilot flow range between 7-10 in\u00b3/min (0.11-0.16 L/min), making it suitable for applications requiring precise modulation between two positions without bistability.

Pilot-operated, 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 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.
