The valve carrier is mounted to the end of the manipulator or robot and houses all of the lubrication valves and mixing nozzles. The lubricant and air hoses are brought into the valve carrier and connected to the valve bases. At the front (exit) of the valve carrier are outlet ports fitted with o-rings where the spray tooling can be quick-connected. Exiting the valve carrier will be fine amounts of lubricant highly atomized in air.
To guarantee an optimum spraying result it is necessary to install the lubrication valves and mixing nozzles as near as possible to the spraying heads. This allows for quick response of the lubricant when opening and closing the valves and also reduces the amount of lubricant remaining after the valve when the lubrication cycle is finished.
The valves are mounted on specially designed bases. These bases can be designed to allow multiple lubrication mediums to go out the exit of the valve carrier. For instance, water can be sprayed on the dies first for maximum cooling effect before spraying the lubricant for coating.
