The Sun Hydraulics DPBDLAV (DPBDLAV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This model is characterized by its ability to switch between ports 1 and 2 while blocking port 3, making it suitable for various hydraulic applications where precise control is necessary. The valve shifts when the pressure differential between port 1 and port 3 exceeds the pre-set threshold, with the pressure at port 3 being directly additive to the valve setting. It is important to note that port 3 may not be suitable as a work port in some circuits, but a four-port version of this valve could offer a solution. The DPBDLAV features interchangeable direct-acting and pilot-operated versions that fit the same cavities and maintain identical flow paths. Port 3 can be blocked to prevent shifting, and while this valve is capable of modulating between two positions, it is not bistable. The model incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. With a cavity size of T-11A and a series designation of 1, this valve has a capacity of up to 7 gallons per minute (28 liters per minute) and operates at a maximum pressure of 5000 psi (350 bar). The factory pressure settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). Maximum leakage at standard fluid viscosity is limited to just one in\u00b3/min at 1000 psi (15 cc/min at 70 bar). For adjustments, it requires up to five full clockwise turns, with an installation torque specification of between 30-35 lbf\u00b7ft (41-47 Nm). The valve weighs approximately .60 lb (.30 kg) and uses Viton seal kits for optimal performance.

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) 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.
- Port 3 can be blocked to prevent the valve from shifting.
- 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.
