The Sun Hydraulics DPCOLDV (Material Number: DPCOLDV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses a pre-set threshold, allowing for precise control in hydraulic systems. Port 4 can be blocked to prevent shifting, while port 3 serves as a work port, enhancing the valve's adaptability in various configurations. The DPCOLDV is interchangeable with direct-acting valves, fitting the same cavities and maintaining identical flow paths. Featuring Sun's floating style construction, this valve minimizes the risk of internal binding due to excessive installation torque or machining variations. It has a capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The maximum pressure at port 3 should be limited to 3000 psi (210 bar) due to fatigue strength limits. Pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), and the valve showcases minimal leakage at specified conditions. The DPCOLDV includes adjustable settings with up to five clockwise turns required for increasing pressure settings. Installation requires specific torque values: the valve hex size is 1-1/8 inches (28.6 mm), and it needs an installation torque between 45-50 lbf-ft (61-68 Nm). With dimensions designed for easy integration, this model weighs approximately .60 lb (0.30 kg) and comes with a Viton seal kit option for enhanced durability in demanding environments.

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.
