OFS-needle shut-off nozzle type NVP (pro)

by the controlled closing and opening the flow canal, the cycle time can be reduced and a more exactly injection process is possible.

APPLICATION FIELDS:
The OFS-needle shut-off nozzle type NVP
is used for processing of thermoplastic
materials and thermoplastic elastomers. An
integrated pneumatic or hydraulic cylinder
activated the shut-off nozzle, whereby the
needle opens and closes the flow channel.
The needle is activated in both directions.
For security, the shut-off nozzle is opened
through emerging overpressure. The nozzle
could be also activated by a machine side
rod.
