The Sun Hydraulics DPBDLKV (DPBDLKV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can operate independently or be used to actuate larger pilot-operated directional cartridges or logic cartridges. It functions by shifting when the pressure differential between port 1 and port 3 exceeds its set threshold. Notably, pressure at port 3 directly affects the valve setting, which may limit its use as a work port in certain circuits; a four-port version may be considered if this is an issue. The DPBDLKV is interchangeable with direct-acting versions, sharing cavity fitment and flow paths. The valve's design includes Sun's floating style construction to minimize internal binding due to installation torque or machining variations. It features a capacity of 7 gpm (28 L/min) with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), and it has a control pilot flow range of 7\u201310 in\u00b3/min (0.11\u20130.16 L/min). Valve leakage is minimal, with a maximum of 1 in\u00b3/min at 110 SUS (24 cSt) and 1000 psi (15 cc/min at 70 bar). Adjustments are made via an internal hex screw, requiring up to five full clockwise turns to increase the setting. The valve hex size measures 7/8 inches (22.2 mm), and installation torque ranges from 30\u201335 lbf\u00b7ft (41\u201347 Nm). The locknut requires torque between 80\u201390 lbf\u00b7in (9\u201310 Nm). Weighing approximately .60 lb (.30 kg), this model utilizes Viton seal kits for reliable performance under demanding conditions.

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.
