The Sun Hydraulics DPBNLDV (DPBNLDV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its preset threshold. Port 4 can be blocked to prevent the valve from shifting, and port 3 serves as a work port. With interchangeable direct-acting and pilot-operated versions, these valves fit the same cavities and maintain consistent flow paths. The DPBNLDV features a maximum operating pressure of 5000 psi (350 bar) and a capacity of 7 gpm (28 L/min). It incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. The valve is not bistable; it modulates between two positions based on pressure settings. For optimal performance, the maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Additional specifications include a control pilot flow of 7-10 in\u00b3/min (0.11-0.16 L/min), maximum valve leakage of 1 in\u00b3/min at 110 SUS (24 cSt), and an adjustment range requiring up to 5\u00bd clockwise turns for setting increases. The installation torque for this model is between 30-35 lbf ft (41-47 Nm), with an adjustment screw internal hex size of ^5/32 in. (4 mm). The DPBNLDV model weighs approximately .60 lb (0.30 kg) and comes with a Viton seal kit for enhanced durability in various applications. This product is ideal for applications requiring reliable modulation within hydraulic systems, ensuring precise control over fluid direction and pressure regulation in various mechanical setups.

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.
