The Sun Hydraulics DPBNKJN (DPBNKJN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or serve to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 can be utilized as a work port. These valves are interchangeable with direct-acting versions, sharing the same cavities and flow paths. The DPBNKJN valve is not bistable but can modulate between two positions. It has a maximum pressure capacity of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min). The valve features Sun's floating style construction, which reduces the risk of internal binding due to excessive installation torque or machining variations in cavity/cartridge setups. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. For applications where pilot pressure exceeds the valve setting and pilot flow becomes significant, a direct-acting version may be preferable as it offers solutions for such conditions. The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum leakage at standard oil viscosity limited to 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\u00b7ft (41 to 47 Nm), and locknut torque should be between 80 and 90 lbf\u00b7in (9 to 10 Nm). The adjustment screw has an internal hex size of .156 inches (4 mm), allowing for precise adjustments with up to five clockwise turns needed to increase settings.

Normally closed, 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.
