The Sun Hydraulics DPBMKJN (DPBMKJN) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be utilized independently or to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a pre-set threshold. Notably, port 4 can be blocked to prevent valve shifting, while port 3 can serve as a work port. The valve is not bistable but capable of modulating between two positions. It features interchangeable direct-acting and pilot-operated versions that fit the same cavities and have identical flow paths. The DPBMKJN model incorporates Sun's floating style construction to reduce the risk of internal component binding due to excessive installation torque or cavity/cartridge machining variations. The maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), and maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Additional specifications include control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with a maximum valve leakage of 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). The adjustment screw requires up to five full clockwise turns to increase the setting, and the valve's hex size measures .78 inches (22.2 mm). The installation torque ranges from 30 to 35 lbf\u00b7ft (41 to 47 Nm), while the locknut torque ranges from 80 to 90 lbf\u00b7in (9 to 10 Nm). This model weighs .60 lb (.30 kg) and uses Viton seal kits for optimal performance in hydraulic systems.

Normally open, pilot-operated, 2-way directional cartridges 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.
