The Sun Hydraulics DPCNLDN (DPCNLDN) 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 the set threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port. The valve's design allows for interchangeability between direct-acting and pilot-operated versions due to shared cavity and flow path specifications. This model incorporates Sun's floating style construction, which helps minimize internal binding from excessive installation torque or machining variations. It boasts a maximum operating pressure of 5000 psi (350 bar) and a capacity of 15 gpm (60 L/min). The valve's factory pressure settings are established at 4 gpm (15 L/min), with a control pilot flow ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). Maximum leakage is limited to 1 in\u00b3/min at 110 SUS (24 cSt) under a pressure of 1000 psi (70 bar). The DPCNLDN model features an adjustment screw with an internal hex size of 5/32 inches (4 mm) and requires up to five clockwise turns to increase the setting. Installation torque ranges from 45 to 50 lbf ft (61 to 68 Nm), while the locknut hex size is set at 9/16 inches (15 mm) with a torque requirement of 80 to 90 lbf in (9 to 10 Nm). This cartridge valve is suitable for applications requiring precise modulation between two positions without bistable functionality, making it ideal for systems where fatigue strength limits need consideration due to high pressures at port 3, capped at a maximum of 3000 psi (210 bar).

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.
