The CVCS25D320 cartridge component is produced by Vickers for the Cartridge Valves series and functions as a cartridge valve cover in hydraulic automation. It handles directional control through a size 03 pilot interface, matching a directional insert that uses a 1 : 1.5 ratio for balanced flow. The body suits NG 25 cavities and is configured as normally open, so fluid passes freely until pilot pressure shifts the element. A rated flow capacity of 590 L/min supports high-volume circuits, and the assembly withstands system pressures up to 350 bar without derating.
Pilot oil approaches in the ISO orientation, while the gauge port is tapped with an SAE thread for straightforward instrumentation. Buna-N seals contain operating fluid over a temperature range from −20 °C to 70 °C. The cover measures 86.106 mm in length, 89.154 mm in width, and 54.864 mm in height, keeping the footprint compact for manifold mounting. These geometric values, combined with the specified port arrangement, let the valve drop into standardized stacks without modification.
