The Sun Hydraulics DPCCOBN (Material Number: DPCCOBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device with port 1 blocked and ports 2 to 3 open, making it suitable for use either independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 being directly additive to the valve\u2019s setting. However, this configuration may restrict the usability of port 3 as a working port in certain circuits, in which case, a four-port version could be considered. This valve features interchangeable direct-acting and pilot-operated versions that fit identical cavities and maintain consistent flow paths. Port 3 can be blocked to prevent unwanted shifting of the valve. Notably, this model is not bistable but is capable of modulating between two positions. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar) due to fatigue strength constraints rather than hydraulic operating limits. The DPCCOBN incorporates Sun's floating style construction to reduce the risk of internal part binding from excessive installation torque or variations in cavity/cartridge machining. It has a capacity of up to 15 gpm (60 L/min) with factory pressure settings established at a flow rate of 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16\u20130.25 L/min), while maximum valve leakage at standard conditions is capped at one in\u00b3/min per thousand psi (15 cc/min per seventy bar). Installation requires specific torques for both the valve and locknut components, ensuring reliable operation within its intended 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 3 exceeds the setting.
- Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration, the 4 port version of this valve may be a solution.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Port 3 can be blocked to prevent the valve from shifting.
- 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.
