The Sun Hydraulics DPBAOAV (Material Number: DPBAOAV) is a normally open, pilot-operated, 2-way directional cartridge valve designed for moderate flow circuits. It is versatile in its application, capable of functioning independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve activates when the pressure differential between port 1 and port 3 surpasses the preset value, with pressure at port 3 directly adding to this setting. However, due to potential limitations, port 3 may not be suitable as a work port unless using the 4-port version of this valve. This model features interchangeable direct-acting and pilot-operated versions that fit identical cavities and maintain consistent flow paths. The valve's maximum operating pressure is rated at 5000 psi (350 bar), with a capacity of 7 gpm (28 L/min). It incorporates Sun's floating style construction to reduce the risk of internal binding from excessive installation torque or variations in cavity/cartridge machining. The DPBAOAV valve is adjustable with up to 5.5 clockwise turns to increase settings, featuring a hex size of .78 inches (22.2 mm) for installation torque between 30-35 lbf ft (41-47 Nm). Additional specifications include a factory pressure setting established at 4 gpm (15 L/min), control pilot flow ranging from .11-.16 L/min, and maximum valve leakage at one in\u00b3/min under specific conditions. This model is not bistable; it modulates between two positions and should be considered when pilot flow exceeds the valve setting, as this may affect performance. For applications where this is an issue, opting for the direct-acting version could be beneficial. The seal kit for this cartridge uses Viton material for enhanced durability and reliability in various operational conditions.

Normally open, 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.
- 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.
