The Sun Hydraulics DPCDLWN (DPCDLWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile valve can function independently or be used to actuate larger pilot-operated or logic cartridges. It operates by shifting when the pressure differential between port 1 and port 3 exceeds a specific setting, with pressure at port 3 being directly additive to the valve setting. Although port 3 can be blocked to prevent shifting, it should not exceed a maximum pressure of 3000 psi due to fatigue strength limits. The DPCDLWN is not bistable and can modulate between two positions, offering flexibility in various applications. The valve features Sun's floating style construction, which minimizes internal part binding caused by excessive installation torque or cavity machining variations. It fits T2A cavities and belongs to Series 2 with a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). The control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), while the maximum valve leakage at standard viscosity is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Installation requires specific torque settings for both the valve and locknut, ensuring secure and reliable operation. The DPCDLWN includes an adjustment screw for fine-tuning the setting, with up to five clockwise turns available for increased adjustment. The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for effective sealing performance.

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.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- 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.
