The Sun Hydraulics DPCNLWV (DPCNLWV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a specific setting, with port 4 capable of being blocked to prevent shifting. Additionally, port 3 can serve as a work port. The DPCNLWV model is interchangeable with direct-acting versions, fitting the same cavities and maintaining identical flow paths. The pressure at port 4 directly adds to the valve setting, although the valve itself is not bistable and can modulate between two positions. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits rather than hydraulic operating limits. When pilot pressure surpasses the valve setting, pilot flow may need consideration; if this becomes an issue, opting for a direct-acting version may be beneficial. This model incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or machining variations. Key specifications include a cavity type T22A, series number 2, and a capacity of 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min (1000 psi or approximately 15 cc/min at 70 bar). The adjustment mechanism allows for up to five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments provided for optimal performance and reliability.

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.
