The Sun Hydraulics DPCCKHV (DPCCKHV) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It functions by blocking one port while allowing flow between the other two, making it suitable for use either independently or to actuate larger pilot-operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 3 surpasses its setting, with pressure at port 3 directly adding to the valve setting. This feature implies that port 3 may not be viable as a work port in certain circuits; however, a 4-port version could address this limitation. Both direct-acting and pilot-operated versions of these valves are interchangeable as they fit the same cavities and have identical flow paths. Port 3 can be blocked to prevent shifting, and while this valve is not bistable, it can modulate between two positions. The maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength limits. Pilot flow considerations arise when pilot pressure exceeds the valve setting; in such cases, a direct-acting version might be preferable. The valve incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. Key specifications include a T2A cavity, Series 2 designation, and a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at 4 gpm (15 L/min), with a maximum operating pressure of up to 5000 psi (350 bar). Control pilot flow ranges from 10-15 in\u00b3/min (0.16-0.25 L/min), with maximum leakage at approximately 1 in\u00b3/min (1000 psi or about 15 cc/min at 70 bar). Adjustment involves up to five clockwise turns, with specific torque requirements for installation and locknut adjustments. 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 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.
