The Sun Hydraulics DPBDCWN (DPBDCWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component functions primarily by opening from port 1 to port 2 while blocking port 3, making it ideal for use in applications that require controlled switching and modulation between two positions. The valve shifts when the pressure differential between port 1 and port 3 exceeds the preset threshold. It's important to note that pressure at port 3 directly affects the valve setting, potentially limiting its use as a work port in certain circuits; for these cases, a four-port version may be more suitable. This valve is interchangeable with direct-acting versions, sharing the same cavity and flow paths. It incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. With a capacity of up to 7 gpm (28 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model ensures reliable performance in demanding environments. The DPBDCWN features an adjustable setting mechanism with up to five clockwise turns available to increase the setting, providing flexibility in various operational scenarios. The control pilot flow ranges from 7 to 10 cubic inches per minute (0.11 to 0.16 L/min), while maximum valve leakage is limited to just one cubic inch per minute at 1000 psi (15 cc/min at 70 bar). Installation requires specific torque values: valve installation torque is between 30-35 lbf ft (41-47 Nm), and locknut torque is set at 80-90 lbf in (9-10 Nm). Overall, the Sun Hydraulics DPBDCWN offers robust performance with precise control capabilities for hydraulic systems requiring efficient directional control solutions.

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.
