The Sun Hydraulics DPCBKHN (DPCBKHN) is a normally closed, pilot-operated, 2-way directional cartridge designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated directional or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 exceeds its set value, with pressure at port 3 being directly additive to the valve's setting. It is important to note that port 3 may not be suitable as a work port due to this characteristic; however, a 4-port version of the valve could address this limitation. This valve is capable of modulating between two positions and should not be considered bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. For applications where pilot flow becomes a concern once pilot pressure exceeds the valve setting, switching to a direct-acting version might be beneficial. The DPCBKHN incorporates Sun's floating style construction, reducing the risk of internal parts binding from excessive installation torque or variations in cavity/cartridge machining. It fits into a T-2A cavity and belongs to Series 2 with a capacity of handling up to 15 gpm (60 L/min). The factory pressure settings are established at 4 gpm (15 L/min), with maximum operating pressures reaching up to 5000 psi (350 bar). The control pilot flow ranges between 10 - 15 in\u00b3/min (0.16 - 0.25 L/min), and maximum valve leakage is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The valve also features adjustable settings with specific torque requirements for installation and adjustment components.

Normally closed, pilot-operated, 2-way directional cartridges 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.
- 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.
