The Sun Hydraulics DPBDLDV (DPBDLDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This valve facilitates a switching function where ports 1 and 2 are open and port 3 is blocked, making it suitable for applications requiring precise control over fluid direction. It can be used independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds the pre-set threshold, with pressure at port 3 being directly additive to this setting. This feature implies that port 3 might not be suitable as a work port unless using a four-port version of the valve. The DPBDLDV model incorporates Sun's floating style construction, which minimizes internal binding due to installation torque or machining variations. It fits into a T-11A cavity and has a series capacity of 7 gpm (28 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). The control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), while maximum valve leakage is specified at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). For adjustments, the valve allows up to five clockwise turns to increase setting, with specific torque requirements for installation and locknut adjustments. Weighing approximately .60 lb (0.30 kg), this model also utilizes Viton seal kits for enhanced durability and compatibility with hydraulic fluids.

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.
