The Sun Hydraulics DPBBLEN (DPBBLEN) 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 or logic cartridges. The valve actuates when the pressure differential between port 1 and port 3 surpasses the preset threshold, noting that pressure at port 3 directly influences the valve setting. It is important to consider that port 3 may not be suitable as a work port in certain circuit designs; a four-port version might address such concerns. Both direct-acting and pilot-operated variants are interchangeable, sharing cavity dimensions and flow paths. This model is not bistable but can modulate between two positions as required. When pilot pressure exceeds the set level, pilot flow becomes a factor; users should refer to performance curves for insights into pilot consumption relative to load pressure above the valve setting. In scenarios where this poses an issue, opting for the direct-acting version could be beneficial. The DPBBLEN incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into a T-11A cavity and belongs to Series 1 with a capacity of 7 gpm (28 L/min). The 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 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage stands at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). The model features an adjustment mechanism with up to five clockwise turns for increased settings and requires specific installation torque values for optimal performance.

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.
