The Sun Hydraulics DPCNLBV (DPCNLBV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate 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, with the option to block port 4 to prevent shifting and utilize port 3 as a work port. Notably, direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and maintaining identical flow paths. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength limitations rather than hydraulic operating constraints. The DPCNLBV model incorporates Sun's floating style construction, which minimizes potential internal binding caused by excessive installation torque or variations in cavity/cartridge machining. It has a capacity of 15 gpm (60 L/min) with factory pressure settings established at 4 gpm (15 L/min). The valve can handle a maximum operating pressure of up to 5000 psi (350 bar), with control pilot flows ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). It features an adjustment mechanism that allows for up to five clockwise turns to increase the setting, while maintaining minimal leakage rates. This model is equipped with several specific dimensions for installation and adjustment: a hex size of 1-1/8 inches (28.6 mm), an installation torque requirement of 45-50 lbf\u00b7ft (61-68 Nm), an internal hex size of adjustment screw at 5/32 inches (4 mm), and locknut hex size at 9/16 inches (15 mm) with a locknut torque range of 80-90 lbf\u00b7in (9-10 Nm). The DPCNLBV weighs approximately .60 lb (.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.
