The Sun Hydraulics DPBCOHN (DPBCOHN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve features a configuration where port 1 is blocked and ports 2 to 3 are open, making it effective in switching operations. It can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses the set threshold, with port 3's pressure being directly additive to the valve setting. This feature implies that port 3 may not be suitable as a work port unless using the four-port version of this valve. The DPBCOHN incorporates Sun's floating style construction, which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. It fits into cavity T-11A and is part of series 1, with a capacity of handling up to 7 gallons per minute (28 liters per minute). The maximum operating pressure is rated at 5000 psi (350 bar), and it has a control pilot flow range of 7 to 10 inches per minute (0.11 to 0.16 liters per minute). The valve allows for adjustments via an internal hex screw, with settings increasing through clockwise turns. This cartridge valve is not bistable but capable of modulating between two positions depending on pilot pressure exceeding the set value. For applications where pilot flow might be a concern above the valve setting, considering performance curves for pilot consumption versus load pressure is advisable. If necessary, opting for the direct-acting version could resolve potential issues related to pilot flow consumption.

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.
