The Sun Hydraulics DPBOKEV (DPBOKEV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It can be utilized individually or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve functions by shifting when the pressure differential between port 1 and port 4 surpasses the preset level, with port 4 being blockable to prevent shifting and port 3 serving as a work port. Both direct-acting and pilot-operated versions are interchangeable, fitting the same cavities and flow paths. Pressure at port 4 adds directly to the valve's setting, allowing modulation between two positions rather than bistable operation. The maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limits. If pilot flow becomes an issue when exceeding the valve setting, a direct-acting version may be preferable. The DPBOKEV incorporates Sun's floating style construction to minimize internal binding from excessive installation torque or machining variations. It fits into cavity T21A, belongs to series 1, and has a capacity of 7 gpm (28 L/min), with factory settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Valve leakage is minimal at a maximum of 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). Adjustment involves up to five clockwise turns, with specific torque requirements for installation and locknut adjustments provided for precision setup. This model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit for optimal performance in hydraulic systems requiring reliable directional control under varying pressures.

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.
