The Sun Hydraulics DPBCLWN (DPBCLWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can be used independently or to actuate larger pilot-operated or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 exceeds its set value, with pressure at port 3 being directly additive to the valve's setting. It's important to note that port 3 may not be suitable as a work port in certain circuits, and a 4-port version of this valve might be necessary in such cases. The DPBCLWN is interchangeable with direct-acting valves as they share the same cavities and flow paths, offering flexibility in application. Port 3 can also be blocked to prevent shifting if required. This model is not bistable and can modulate between two positions based on pilot pressure exceeding the valve setting. Users should consider pilot flow consumption at high load pressures, and if this becomes problematic, switching to a direct-acting version may provide a solution. The valve incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a capacity of 7 gpm (28 L/min), and factory pressure settings established at 4 gpm (15 L/min). Valve leakage is minimal at 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Installation requires specific torque settings, with an adjustment screw internal hex size of 5/32 inches (4 mm) and locknut torque ranging from 80-90 lbf\u00b7in (9-10 Nm). The model weighs .60 lb (.30 kg) and uses Viton seal kits for maintenance.

Pilot-operated, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.
