The Sun Hydraulics DPCNKWV (DPCNKWV) 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 activates when the pressure differential between port 1 and port 4 surpasses the pre-set threshold. The design allows port 4 to be blocked to prevent shifting and utilizes port 3 as a work port, while maintaining interchangeability with direct-acting versions due to identical cavity and flow path configurations. The valve is capable of modulating between two positions and is not bistable, with a maximum pressure limit at port 3 of 3000 psi (210 bar) due to fatigue strength considerations. It features Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. This valve fits into a T22A cavity, belongs to series 2, and has a capacity of up to 15 gpm (60 L/min). Its factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), while maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustment requires up to five clockwise turns, with specific torque settings for installation and adjustment components provided for precision handling. The model weighs approximately .60 lb (.30 kg), and it includes Viton seal kits for enhanced durability under various operational 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.
