Chains that are not pre-tensioned to specification shorten the service life of the undercarriage parts and can even damage the transmission and undercarriage components. To prevent this, we have developed our own safety and multifunction valves.


Our safety valves offer you decisive advantages:

  • maintenance-free and installed in the shortest possible time

  • reduction of repair-related downtimes

  • factory pre-setting of the pressure levels possible based on your machine configuration


Our patented multifunction valves offer you additional advantages:

  • direct measurement of the preload force using a manometer

  • integrated grease flow control to avoid overfilling

  • environmentally friendly quick closing properties

  • optimum access for the operator thanks to 360° rotation

  • assembly with standard tools
