The Sun Hydraulics DPBBKEN (Material Number: DPBBKEN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold. It is important to note that pressure at port 3 directly adds to the valve's setting, which may limit its use as a work port in certain circuit configurations; a four-port variant could provide a solution in such cases. The DPBBKEN model features interchangeability between direct-acting and pilot-operated versions, allowing them to fit the same cavities and share identical flow paths. It is not bistable but can modulate smoothly between two positions as needed. When pilot pressure exceeds the valve's setting, consideration of pilot flow becomes necessary\u2014consult performance curves for details on pilot consumption relative to load pressure above the valve setting. For situations where this presents an issue, opting for a direct-acting version may be advantageous. This model incorporates Sun's floating style construction to minimize binding risks due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a T-11A cavity, Series 1 classification, and a capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), and maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The model weighs .60 lb (.30 kg) and uses Viton seal kits under part number 990011006.

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.
- 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.
