The Sun Hydraulics DPCOKBV (DPCOKBV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device with one port blocked and allows flow between two other ports. This valve can operate independently or serve to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds its setting, with port 4 optionally blockable to prevent shifting and port 3 usable as a work port. Both direct-acting and pilot-operated versions are interchangeable, sharing the same cavities and flow paths. The pressure at port 4 directly adds to the valve's setting, but it is not bistable, allowing modulation between positions. The DPCOKBV has a maximum operating pressure of 5000 psi (350 bar) and should limit maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength limits. It features Sun's floating style construction, reducing internal binding risks due to installation torque or machining variations. With a capacity of 15 gpm (60 L/min), this valve has factory pressure settings established at a flow rate of 4 gpm (15 L/min). Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum leakage at specified conditions being minimal. For installation, the required torque specifications include a valve hex size of 1-1/8 inches (28.6 mm) with an installation torque range of 45-50 lbf ft (61-68 Nm). The adjustment screw uses an internal hex size of 5/32 inches (4 mm), while the locknut requires a hex size of 9/16 inches (15 mm) tightened to a torque of 80-90 lbf in (9-10 Nm). This model weighs approximately .60 lb (.30 kg) and incorporates Viton seal kits for durability in various applications.

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.
