The Sun Hydraulics DPCOLAV (DPCOLAV) 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 directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 surpasses the set threshold, with port 4 being blockable to prevent shifting. Port 3 serves as a work port and should not exceed a maximum pressure of 3000 psi due to fatigue strength limits. The DPCOLAV is not bistable, allowing it to modulate between two positions, and features interchangeable direct-acting and pilot-operated versions that fit the same cavities and have identical flow paths. This model incorporates Sun's floating style construction, minimizing the risk of internal parts binding from excessive installation torque or variations in cavity/cartridge machining. It fits cavity T22A, belongs to series 2, and has a capacity of 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 maximum valve leakage at 110 SUS (24 cSt) is limited to 1 in\u00b3/min at 1000 psi (15 cc/min at 70 bar). Adjustments can be made by turning clockwise up to five times to increase settings. For installation, the valve requires a hex size of 1-1/8 inches (28.6 mm) with an installation torque between 45\u201350 lbf\u00b7ft (61\u201368 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) and requires a torque of 80\u201390 lbf\u00b7in (9\u201310 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for maintenance.

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.
