Spring cap nozzle EN 37
 

 

The decompression nozzle (needle valve) prevents dripping from thermoplastics when the spraying process is complete.

The moving needle is pressed onto an internal spring (enclosed design) by the melt pressure. The nozzle opens at a melt pressure of 50 bar and is closed as the pressure drops, due to the spring tension. Thanks to its opimised flow geometry, the spring cap nozzle operates with minimal pressure loss.

The compact, easy-to-disassemble construction enables efficient heat transfer and fast, effective cleaning.

All parts come in a wear-resistant design and can also be ordered as individual components. It is not necessary to cange settings when exchanging parts.

The spring cap nozzle can be manufactured and supplied ready for installation according to your own requirements (nozzle radius, hole diameter, connection thread and screw diameter) complete with heating nad and integrated sensor.
