Extrusion valve

In many cases the extrusion valves of series MMDV and MMDV LV/KV give the opportunity to solve application jobs by their low weight and their small dimensioned construction, especially for the installation in machines or robots. The very small dimensions of valves give the opportunity to install them with very low space requirements. With the long nozzles (LV) the valves can be sloped to each other such to achieve narrow nozzle distances.

These valves are suitable for the application of glues, adhesives, oils and sealing compounds. Depending on nozzle dimension, fluids of different viscosities can be applied.

The extrusion valves of series MMDV are designed for material pressures up to 100 bar.

The control of valve is reached through two separate air connections. One for the opening of the needle and one for the closing of the needle. This has to be done via an external pneumatic valve.
