The Sun Hydraulics DPCNLAV (DPCNLAV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a preset threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port. This model is interchangeable with direct-acting versions, sharing the same cavities and flow paths. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limitations. The valve features Sun's floating style construction to minimize internal binding caused by excessive installation torque or cavity machining variations. The DPCNLAV fits into a T22A cavity and belongs to Series 2 with a capacity of 15 gpm (60 L/min). Factory pressure settings are determined at a flow rate of 4 gpm (15 L/min), and it can handle a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum valve leakage at 110 SUS /24 cSt being limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made by turning the screw clockwise up to five turns, with specific torque requirements for installation and locknut adjustments. This cartridge valve is not bistable but capable of modulating between two positions, making it versatile in applications requiring precise control over fluid direction under varying pressures. If pilot flow consumption becomes an issue above the valve setting, opting for the direct-acting version may provide a solution.

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.
