Overview of valve technology


Our current lubricant valves have the following advantages over their predecessors, developed by Mr. Jerkel, some of which are still used by our competitors:

  1. Dead space free
  2. Modular
  3. Pre-controlled opening and closing
  4. faster maintenance

Based on these advantages, we have also adopted the design features for all our other valves: circulation valves, pressure build-up valves, purge valves, insert valves and the new integrated spray-mixing blocks.

The design principle and the advantages of dead space free valves can best be explained in a comparison of the valves:


 Old design
(The old construction is still used by the most of our competitors)

New design


Valve with dead space


Valve without dead space

IIn contrast to our old design with basic block and tap hole in the actual valve chamber, the valve chamber is completely flushed when circulating in our new valves. This means that there are no "dead spaces" in which sediments can deposit!

In contrast, with our old valves, the valve seat has to be completely removed to the front! (about 15 minutes work). In addition, the valve needle lift actually needs to be recalibrated With our new valves, the seal carrier (1) can be exchanged after loosening 4 allen screws (2) (about 3 minutes of work).

Very complicated ....! Adjustment during production not possible!

Simply adjust rear hexagon screw – done!

Single-acting, therefore increased closing and opening times Double-acting, closing time> 0.003 seconds, in case of failure of the compressed air still closing by spring force..
