The Sun Hydraulics DPBNLEV (DPBNLEV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated or logic cartridges. The valve is engineered to shift when the pressure differential between port 1 and port 4 surpasses the preset threshold, with an option to block port 4 to prevent shifting. Port 3 serves as a work port with a maximum pressure limit of 3000 psi due to fatigue strength considerations. This valve is capable of modulating between two positions and is not bistable. It incorporates Sun's floating style construction, minimizing internal binding risks from excessive installation torque or machining variations. The DPBNLEV fits into cavity T-21A and belongs to Series 1 with a capacity of 7 gallons per minute (28 liters per minute). Factory pressure settings are established at 4 gallons per minute (15 liters per minute), and it can operate at a maximum pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 inches per minute (0.11 to 0.16 liters per minute), while maximum valve leakage at standard conditions is limited to 1 inch per minute (15 cc/min). For adjustments, the setting can be increased by turning clockwise up to five turns. Installation specifics include a valve hex size of .78 inches (22.2 mm) and an installation torque requirement of 30-35 lbf-ft (41-47 Nm). The adjustment screw features an internal hex size of .156 inches (4 mm), while the locknut hex size is .5625 inches (15 mm) with a torque specification of 80-90 lbf-in (9-10 Nm). The model weighs .60 pounds (.30 kg) and utilizes Viton seal kits for cartridge sealing needs.

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.
