The Sun Hydraulics DPCOKWN (DPCOKWN) is a pilot-operated, 3-way directional cartridge valve designed for moderate flow circuits. It features one blocked port and an open path between ports 2 and 3, making it suitable for applications that require switching capabilities. This valve can be used independently or in conjunction with larger pilot-operated directional or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the preset threshold, with port 4 capable of being blocked to prevent shifting. Port 3 can serve as a work port, and the design allows interchangeability between direct-acting and pilot-operated versions due to shared cavity dimensions and flow paths. The DPCOKWN model incorporates Sun's floating style construction to minimize internal binding risks from excessive installation torque or machining variations. It has a maximum operating pressure of 5000 psi (350 bar) and a capacity of 15 gpm (60 L/min). The pressure at port 4 adds directly to the valve setting, allowing modulation between its two positions rather than bistable operation. Maximum pressure at port 3 should not exceed 3000 psi (210 bar) due to fatigue strength considerations. Factory pressure settings are established at a flow rate of 4 gpm (15 L/min), with control pilot flow measuring between 10-15 in\u00b3/min (0.16-0.25 L/min). The valve's leakage rate is minimal, at just 1 in\u00b3/min per 1000 psi (15 cc/min per 70 bar), ensuring efficient operation. Adjustments can be made via an internal hex screw, with up to five clockwise turns available to increase the setting. This robust component weighs approximately .60 lb (.30 kg) and requires specific installation torque specifications for optimal performance.

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.
