Spray Mixing Block

SprühmischblockHauptThe spray mixing blocks were specially developed for warm forging. Due to the modular and maintenance-friendly design, a wide variety of possible combinations can be realized. The spray pad is based on our proven JB14XX series valves and has a valve seat cartridge insert. The atomizing air is acidified via external membranes and can be individually adjusted on request.

Dosing valve JB1401 / JB1403

image002The high pressure valves JB1401 and JB1403 have been specially developed for the metered spraying of liquids with a high content of solids.

The valve has been used with great success for more than ten years (1.3 million spray cycles without gasket replacement) and replaced the old Jerkel series, which is still used by our competitors (EJ1441 / EJ1451 + Bemers / Unitec types).

The special design (dead space free) allows the material (e.g., graphite-containing lubricants) to pass directly the valve seats, from the flow, through all the valves, to the return port.

All JERKO valves are characterized by their dead-space-free design and are therefore useable for graphite-containing lubricants.

In addition to that, the Jerko valves have the shortest response times (less than 0.05 seconds). If the compressed air fails, the Jerko valves close by spring-return - for maximum safety!

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:

Plate sprayheads

SprühkopfHauptPlate spray heads are ideal for rapid and reproducible spraying of dies in the forging industry. The Jerko plate spray heads are designed and manufactured for each die size in close consultation with the customer. By simply changing the spray plates, the spray pattern can be individually adapted to the contours of the dies.

The swirl pots and swirl disks used by Jerko and precisely matched in terms of geometry distribute the lubricant previously injected into the air flow with extremely high dynamics under the spray plate so that an exact spray pattern is created in all areas of the spray plate.
