The Sun Hydraulics DPBBLAN (DPBBLAN) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It serves as a versatile switching device that can function independently or actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses the set threshold. Notably, pressure at port 3 adds directly to the valve setting, which might restrict its use as a work port in some circuits; in such cases, a 4-port version could be more appropriate. The DPBBLAN is interchangeable with direct-acting versions as they share the same cavities and flow paths. This model is not bistable and can modulate between two positions. Should pilot pressure exceed the valve setting, pilot flow becomes a consideration\u2014refer to performance curves for details on pilot consumption versus load pressure above the setting. If excessive pilot flow poses an issue, opting for a direct-acting version might be beneficial. The valve incorporates Sun's floating style construction to minimize internal part binding from installation torque or cavity-cartridge machining variations. Key specifications include a T11A cavity, Series 1 designation, 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 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made via an internal hex screw with specific torque requirements for installation and locknut adjustments. The DPBBLAN weighs approximately .60 lb (0.30 kg) and utilizes Viton seal kits for maintenance needs.

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.
