The Sun Hydraulics DPBNCEV (DPBNCEV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 exceeds a predetermined setting. Notably, port 4 can be blocked to prevent the valve from shifting, while port 3 serves as a work port with a maximum pressure limit of 3000 psi (210 bar) due to fatigue strength limits. The valve is not bistable and can modulate between two positions. The DPBNCEV features Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. It fits into T21A cavities and has a series capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), and it offers control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Valve leakage at maximum viscosity is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). For adjustment, the valve requires up to five clockwise turns to increase the setting, with an installation torque specification of 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of ^5\u204432 in. (4 mm), while the locknut hex size is ^9\u204416 in. (15 mm) and requires a torque of 80-90 lbf in. (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seals for optimal performance in hydraulic systems.

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.
