The Sun Hydraulics DPBNLBN (DPBNLBN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses a predetermined setting. The valve's design allows for port 4 to be blocked to prevent shifting, while port 3 can serve as a work port. Notably, the direct-acting and pilot-operated variants of these valves are interchangeable, fitting the same cavities and maintaining identical flow paths. The valve integrates Sun's floating style construction to reduce the risk of internal binding due to excessive installation torque or machining variations. It has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). The maximum pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength considerations. The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), ensuring reliable performance in various applications. This valve is capable of modulating between two positions rather than being bistable, offering flexibility in operation. Its control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), with maximum leakage at specified conditions being just 1 in\u00b3/min (1000 psi/15 cc/min/70 bar). Installation specifications include a valve hex size of .78 inches (22.2 mm) and an installation torque requirement of 30-35 lbf\u00b7ft (41-47 Nm). For adjustments, the screw internal hex size is .532 inches (4 mm), while the locknut hex size is .916 inches (15 mm), with locknut torque between 80-90 lbf\u00b7in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit for optimal sealing performance.

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.
