The Sun Hydraulics DPBCOKN (Material Number: DPBCOKN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve type is typically used to control the flow between ports, with port 1 blocked and ports 2 to 3 open. It can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a predetermined setting, with pressure at port 3 directly contributing to this setting. Due to this characteristic, port 3 may not be suitable as a work port in some circuits, and an alternative could be the four-port version of this valve. The direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. Port 3 can be blocked if it's necessary to prevent the valve from shifting. Notably, this valve is not bistable; it can modulate between two positions depending on pilot pressure relative to the valve setting. Users should consider pilot flow consumption when pilot pressure exceeds the valve setting; if excessive, switching to a direct-acting version might be beneficial. The Sun Hydraulics DPBCOKN incorporates floating-style construction that minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. The T11A cavity series offers a capacity of up to 7 gpm (28 L/min) with factory pressure settings established at a flow rate of 4 gpm (15 L/min). It is rated for a maximum operating pressure of 5000 psi (350 bar) with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). This robust design ensures reliable performance in various hydraulic applications where precise directional control is essential.

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.
