The Sun Hydraulics DPCOLDN (DPCOLDN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can be utilized independently or to actuate larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the preset threshold, with the option to block port 4 to prevent this shift. Port 3 serves as a work port and should not exceed a maximum pressure of 3000 psi (210 bar) due to fatigue strength considerations. The valve's design incorporates Sun's floating style construction, which minimizes internal binding risks from excessive installation torque or machining variations. The DPCOLDN model fits T-22A cavities and belongs to Series 2, with a capacity of handling up to 15 gpm (60 L/min). It boasts a maximum operating pressure of 5000 psi (350 bar) and features adjustable settings established at a flow rate of 4 gpm (15 L/min). Control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min), while maximum leakage at standard viscosity is limited to 1 in\u00b3/min/1000 psi (15 cc/min/70 bar). The adjustment mechanism allows for up to 5.5 clockwise turns to increase the setting, with specific torque requirements for both installation and locknut adjustments. This non-bistable valve modulates between two positions, offering flexibility in various hydraulic applications. It is interchangeable with direct-acting versions that share similar cavities and flow paths, allowing for seamless integration into existing systems where modulation or precise control is required.

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 4 exceeds the setting.
- Port 4 can be blocked to prevent the valve from shifting.
- Port 3 can be used as a work port.
- Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
- Pressure at port 4 is directly additive to the setting of the valve.
- 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.
