The Sun Hydraulics DPBNCDN (DPBNCDN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve 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 exceeds the predetermined setting, with the option to block port 4 to prevent shifting. Port 3 serves as a work port and can handle a maximum pressure of 3000 psi (210 bar) due to fatigue strength limits. The valve is capable of modulating between two positions and is not bistable. It features Sun's floating style construction, which minimizes internal part binding from excessive installation torque or machining variations. The DPBNCDN fits into cavity T-21A and belongs to series 1 with a capacity of 7 gpm (28 L/min). Its factory pressure settings are established at 4 gpm (15 L/min), and it can withstand a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage is limited to 1 in\u00b3/min at 110 SUS (24 cSt) under a pressure of 1000 psi (70 bar). The valve's adjustment requires up to five clockwise turns, with specific torque values for installation and locknut adjustments provided for optimal performance. This cartridge valve weighs approximately .60 lb (0.30 kg) and includes a Viton seal kit, part number: 990021006. It is ideal for applications requiring precise control over hydraulic circuits where modulation between states without bistability is necessary, offering reliable performance under varying conditions.

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.
