The Sun Hydraulics DPBDLEN (DPBDLEN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve functions by opening ports 1 to 2 while blocking port 3, and it can be used independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 3 exceeds a preset threshold. It's important to note that pressure at port 3 directly adds to the valve's setting, which may restrict its use as a work port in certain circuits. For applications requiring a work port at this location, consider using the four-port version of this valve. The DPBDLEN features interchangeable direct-acting and pilot-operated versions that fit the same cavities with identical flow paths. Port 3 can be blocked to prevent unwanted shifting of the valve, which is not bistable but capable of modulating between two positions based on pilot pressure exceeding the set value. Pilot flow should be considered when evaluating performance curves for load pressure above the valve setting; if excessive, opting for a direct-acting version might be beneficial. This model incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It fits cavity T-11A with a capacity of up to 7 gpm (28 L/min) and operates at pressures up to 5000 psi (350 bar). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min). The maximum leakage at specified conditions is limited to 1 in\u00b3/min (15 cc/min). Adjustments can increase settings through clockwise turns, with specific torque requirements for installation and locknut adjustments provided for optimal performance and reliability.

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.
