The Sun Hydraulics DPBOCWV (DPBOCWV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve is typically used to switch devices and can function independently or in conjunction with larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 4 surpasses the valve's setting. Port 4 can be blocked to prevent shifting, while port 3 serves as a work port. The valve's design allows for interchangeability with direct-acting versions, as they share the same cavities and flow paths. Notably, this non-bistable valve can modulate between two positions, with a maximum pressure limit of 3000 psi at port 3 due to fatigue strength considerations. The DPBOCWV features Sun's floating style construction, minimizing internal part binding risks from excessive installation torque or cavity/cartridge 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 a flow rate of 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 maximum allowable leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at a pressure of 1000 psi (15 cc/min at 70 bar). Adjustment is achieved through clockwise turns, allowing up to five full rotations to increase the setting. For installation, the valve requires a torque setting between 30 and 35 lbf-ft (41 to 47 Nm), with an adjustment screw internal hex size of ^5/32 inches (4 mm) and a locknut hex size of ^9/16 inches (15 mm), requiring torque between 80 and 90 lbf-in (9 to 10 Nm). The model weighs approximately .60 lbs (.30 kg), and it uses Viton seal kits for cartridge maintenance.

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.
