The Sun Hydraulics DPBCCWN (DPBCCWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions as a switching device, allowing port 2 to open to port 3 while blocking port 1. The valve shifts when the pressure differential between ports 1 and 3 exceeds the predetermined setting, with pressure at port 3 being directly additive to the setting. This feature makes port 3 potentially unsuitable as a work port, suggesting that a 4-port version might be necessary for some applications. The DPBCCWN can be used independently or to actuate larger pilot-operated directional or logic cartridges. This model incorporates Sun's floating style construction, minimizing the risk of internal part binding due to excessive installation torque or machining variations in the cavity or cartridge. It is not bistable and can modulate between two positions based on pilot pressure exceeding the valve setting. If pilot flow becomes an issue, a direct-acting version may be more appropriate. The valve fits T-11A cavities and has a series capacity of 7 gpm (28 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min), and maximum valve leakage at specified conditions is limited to 1 in\u00b3/min (15 cc/min). The DPBCCWN features an adjustment mechanism with up to five clockwise turns required to increase settings and comes with specific torque specifications for both installation and locknut adjustments. The valve weighs approximately .60 lb (0.30 kg) and uses Viton seal kits for maintenance purposes.

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.
