The Sun Hydraulics DPCDKBN (DPCDKBN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses a predetermined setting. Notably, pressure at port 3 adds directly to the valve's setting, which may limit its use as a work port in certain circuits; for such applications, a 4-port version might be more suitable. The DPCDKBN is interchangeable with direct-acting versions, sharing the same cavities and flow paths. It features modulating capability between two positions but is not bistable. The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength considerations rather than hydraulic limits. This valve incorporates Sun's floating style construction to reduce the risk of internal binding from excessive torque or machining variations. With a capacity of 15 gpm (60 L/min) and factory pressure settings established at 4 gpm (15 L/min), it can handle maximum operating pressures up to 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), with maximum leakage at specified viscosity being just 1 in\u00b3/min (15 cc/min). Adjustment is made via an internal hex screw, requiring up to five clockwise turns to increase settings, and secured with a locknut torqued between 80-90 lbf\u00b7in (9-10 Nm). Weighing only .60 lb (.30 kg), this cartridge valve offers robust performance in hydraulic systems requiring reliable directional control under varying pressures and conditions.

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.
- 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.
