The Sun Hydraulics DPBPCWV (Material Number: DPBPCWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It is typically used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds a specific setting, with the option to block port 4 to prevent shifting. Port 3 can be utilized as a work port, and both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities with identical flow paths. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. This valve features Sun's floating style construction, which minimizes internal binding risks due to excessive installation torque or machining variations. It has a capacity of 7 gpm (28 L/min) and operates at a maximum pressure of 5000 psi (350 bar). Factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The valve boasts low leakage rates, with a maximum leakage of just 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments can be made via an internal hex screw, requiring up to five clockwise turns to increase settings. The DPBPCWV model is compact, weighing only .60 lb (0.30 kg), and features a hex size of .78 in. (22.2 mm) for the valve body, with installation torque specifications between 30 and 35 lbf-ft (41-47 Nm). A Viton seal kit is available for this cartridge model under part number: 990021006.

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.
