The Sun Hydraulics DPBPCDV (DPBPCDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, offering versatility in various hydraulic applications. This valve is particularly effective as a standalone unit or when used to actuate larger pilot-operated directional cartridges or logic cartridges. Its operation hinges on the pressure differential between port 1 and port 4, with the valve shifting once the differential exceeds a predefined setting. Port 4 can be blocked to prevent shifting, while port 3 serves as a work port, capable of handling pressures up to 3000 psi (210 bar), though this limit is due to fatigue strength rather than hydraulic operating constraints. The DPBPCDV integrates Sun's floating style construction to reduce internal binding risks caused by installation torque or cavity machining variations. It fits T-21A cavities and boasts a capacity of 7 gpm (28 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure reaches an impressive 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments can be made with up to five clockwise turns, using an internal hex size of 5/32 inches (4 mm), and secured with a locknut that requires a torque of between 80 and 90 lbf-in (9 to 10 Nm). The valve itself weighs .60 lb (.30 kg) and uses Viton seal kits for optimal performance. This model is not bistable but modulates between two positions based on pilot pressure exceeding the valve setting, making it adaptable for various circuit requirements.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
