The Sun Hydraulics DPBDKDN (DPBDKDN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized independently or to actuate larger pilot-operated directional cartridges or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 surpasses a predetermined setting. Notably, pressure at port 3 directly adds to the valve's setting, which may limit its use as a work port in certain circuits. For such scenarios, a 4-port version of this valve could be considered as an alternative. The DPBDKDN model is interchangeable with direct-acting versions, fitting the same cavities and maintaining identical flow paths. Port 3 can be blocked to prevent unwanted shifting of the valve, which is not bistable but capable of modulating between two positions. When pilot pressure exceeds the valve's setting, pilot flow considerations become important; if this poses an issue, opting for a direct-acting version might resolve it. This valve incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The DPBDKDN features a T-11A cavity and belongs to series 1 with a capacity of 7 gpm (28 L/min). It operates at a maximum pressure of 5000 psi (350 bar) and has specific control pilot flow rates and leakage parameters. For installation, it requires specific torque settings and hex sizes for adjustments. The model weighs .60 lb (0.30 kg) and utilizes Viton seal kits for maintenance. This product is ideal for applications where precise modulation between positions is necessary without bistable functionality, ensuring reliable performance in various hydraulic systems.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
