The Sun Hydraulics DPBDLKN (DPBDLKN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component is typically used either 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 the set threshold. However, users should note that pressure at port 3 adds directly to the valve setting, potentially limiting its use as a work port in certain circuits. For such cases, a 4-port version might be more suitable. The DPBDLKN model is interchangeable with direct-acting versions, sharing the same cavities and flow paths, and can be blocked at port 3 to prevent shifting. It is not bistable but can modulate between two positions as required by circuit conditions. The valve incorporates Sun's floating style construction to minimize binding risks due to excessive installation torque or cavity machining variations. It has a capacity of 7 gpm (28 L/min) and operates at pressures up to 5000 psi (350 bar). 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 is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments are made via an internal hex screw with up to five clockwise turns needed for increased settings. The valve has a hex size of .78 inches (22.2 mm) and requires an installation torque of 30-35 lbf ft (41-47 Nm). A Viton seal kit is available for maintenance purposes.

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.
