The Sun Hydraulics DPBOLDV (Material Number: DPBOLDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be utilized 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 its set threshold. Notably, port 4 can be blocked to prevent shifting, and port 3 serves as a work port. Both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and having identical flow paths. The DPBOLDV incorporates Sun's floating style construction, which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The valve has a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar), though the maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. For optimal performance, the control pilot flow ranges between 7-10 in\u00b3/min (0.11-0.16 L/min), with maximum valve leakage at 110 SUS (24 cSt) limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made through a screw with an internal hex size of 5/32 in (4 mm), allowing for up to five clockwise turns to increase settings. The valve's installation torque is specified between 30-35 lbf\u00b7ft (41-47 Nm), with a locknut torque range of 80-90 lbf\u00b7in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses a Viton seal kit for cartridge sealing.

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