The Sun Hydraulics DPBBLBV (DPBBLBV) is a normally closed, pilot-operated, 2-way directional cartridge valve designed for use in moderate flow circuits. This versatile component can function independently or be used to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 surpasses its set threshold. Notably, pressure at port 3 directly adds to the valve's setting, potentially limiting its usability as a work port in certain circuits. In such cases, a 4-port version might be more suitable. Both direct-acting and pilot-operated versions of these valves are interchangeable, sharing identical cavities and flow paths. This particular model is not bistable; it can modulate between two positions based on pilot pressure exceeding the valve setting. Attention should be given to pilot flow when this occurs, as it may impact performance; if so, a direct-acting version could be considered as an alternative. The DPBBLBV incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a T-11A cavity with a capacity of 7 gpm (28 L/min), maximum operating pressure of 5000 psi (350 bar), and factory pressure settings established at 4 gpm (15 L/min). Control pilot flow ranges from 7-10 in\u00b3/min (0.11-0.16 L/min), with maximum valve leakage at 110 SUS (24 cSt) capped at 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar). The adjustment features allow for up to five clockwise turns to increase settings, with specified torque values for installation and locknut adjustments ensuring secure assembly. The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for optimal performance under various conditions.

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.
