Hydraulic change-over valve is mounted with the simple lubricating systems for central greasing as a management control device. When the pressure in the main water reaches a preset value (50 - 350 bar), the system will automatically switch trunk lines a micro switch will signal that the lubrication cycle is completed. After you turn on the pump manifold automatically charges second highway lubrication with lubricant and the cycle repeats. In this way it is possible to very easily manage the operations of the entire lubrication system. Due to its robust construction, the large flow cross-section and a simple management of the entire system, this device is very suitable for use in steel mills, mines, excavators, cement plants where it works seamlessly in the most difficult conditions.
