The Sun Hydraulics DPCNCEV (Material Number: DPCNCEV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a preset threshold. Notably, port 4 can be blocked to prevent shifting, while port 3 serves as a work port. Direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and sharing flow paths. Pressure at port 4 adds directly to the valve setting, allowing modulation between two positions rather than bistable operation. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a capacity of 15 gpm (60 L/min). The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum valve leakage at specified conditions being minimal at just 1 in\u00b3/min (15 cc/min). The valve's adjustment features allow for fine-tuning with up to five clockwise turns needed to increase settings, facilitated by an internal hex adjustment screw. Installation requires specific torque values: the valve installation torque is between 45-50 lbf-ft (61-68 Nm), and the locknut torque ranges from 80-90 lbf-in (9-10 Nm). The design incorporates Sun's floating style construction, reducing the risk of internal parts binding due to excessive installation torque or machining variations within cavities/cartridges. This robust design ensures reliability in various hydraulic applications where precise control is essential.

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.
