The Sun Hydraulics DPBCOCN (DPBCOCN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device, allowing port 2 to open to port 3 while port 1 remains blocked. This valve can operate independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses its set point, with pressure at port 3 being directly additive to the valve setting, which may restrict its use as a work port in certain circuits. If this poses an issue, a four-port version of the valve could be considered. The DPBCOCN is not bistable and can modulate between two positions based on pilot pressure exceeding the valve setting. Pilot flow should be considered when pilot pressure exceeds the setting, and if this becomes problematic, a direct-acting version may be more suitable. The valve features Sun's floating style construction, reducing the risk of internal part binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a cavity type T-11A, series 1 capacity of 7 gpm (28 L/min), maximum operating pressure of 5000 psi (350 bar), and control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). The maximum valve leakage at 110 SUS (24 cSt) is specified at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Installation requires a torque of 30-35 lbf\u00b7ft (41-47 Nm), with adjustments made via an internal hex screw sized at ^5/32 in. (4 mm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for optimal performance.

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.
- 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.
