The Sun Hydraulics DPCOLAN (DPCOLAN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component is engineered to function either independently or in tandem with larger pilot-operated or logic cartridges. The valve activates when the pressure differential between port 1 and port 4 surpasses a predetermined setting, and it can be prevented from shifting by blocking port 4. Port 3 serves as a work port, and both direct-acting and pilot-operated versions of these valves are interchangeable, fitting the same cavities and maintaining identical flow paths. The valve features Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a capacity of 15 gpm (60 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min). It's important to note that maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Control pilot flow ranges from 10 to 15 in\u00b3/min (0.16 to 0.25 L/min), with maximum valve leakage at specified conditions being limited to 1 in\u00b3/min (1000 psi/15 cc/min/70 bar). The adjustment mechanism allows for up to five complete clockwise turns to increase the setting. The valve's installation requires specific torque values: the valve hex size is 1-1/8 in. (28.6 mm), with an installation torque range of 45-50 lbf\u00b7ft (61-68 Nm). Additionally, the adjustment screw internal hex size is set at 5/32 in. (4 mm), while the locknut hex size is fixed at 9/16 in. (15 mm) with a locknut torque requirement of 80-90 lbf\u00b7in. (9-10 Nm). Weighing just .60 lb (.30 kg), this model also comes with an available Viton seal kit 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 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.
