The Sun Hydraulics DPBCOWN (DPBCOWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits, offering versatile applications such as actuating larger pilot-operated or logic cartridges. This valve is characterized by its ability to shift when the pressure differential between port 1 and port 3 surpasses the predefined setting, with pressure at port 3 being directly additive to this setting. Therefore, port 3 may not be suitable as a work port in certain circuits, suggesting that the 4-port version might be more appropriate in such cases. The valve's design allows for interchangeability between direct-acting and pilot-operated versions due to their compatibility with the same cavities and flow paths. Port 3 can also be blocked to prevent shifting, providing flexibility in application. Notably, the DPBCOWN is capable of modulating between two positions instead of being bistable. When pilot pressure exceeds the valve setting, pilot flow becomes an important consideration; performance curves should be consulted for details on pilot consumption versus load pressure above the valve setting. If excessive pilot flow presents issues, opting for a direct-acting version could resolve them. The valve incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or cavity/cartridge machining variations. The DPBCOWN fits into a T-11A cavity with a capacity of 7 gpm (28 L/min) and operates under a maximum pressure of 5000 psi (350 bar). It features factory pressure settings established at 4 gpm (15 L/min), with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). The maximum allowable leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min (15 cc/min) at 1000 psi (70 bar). The valve's hex size measures .78 inches (22.2 mm), requiring an installation torque of 30-35 lbf ft (41-47 Nm).

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.
