The Sun Hydraulics DPCCLWN (DPCCLWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It serves as a switching device where port 1 is blocked and ports 2 to 3 are open, making it suitable for use independently or to actuate larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses the set threshold, with pressure at port 3 being directly additive to the valve setting. This means that port 3 may not be suitable as a work port in certain circuits; in such cases, a 4-port version might be more appropriate. Notably, direct-acting and pilot-operated versions of these valves are interchangeable, sharing the same cavities and flow paths. The DPCCLWN can modulate between two positions and is not bistable. It has a maximum operating pressure of 5000 psi (350 bar) and should limit pressure at port 3 to 3000 psi (210 bar) due to fatigue strength constraints. With a capacity of handling up to 15 gpm (60 L/min), this valve incorporates Sun's floating style construction to reduce internal part binding from excessive installation torque or machining variations. The factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with control pilot flow ranging from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min). The valve features an adjustment mechanism that requires up to five clockwise turns to increase the setting, and it includes specific torque requirements for installation, locknut adjustment, and seal maintenance using Viton material for durability.

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.
- 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.
