Needle valve nozzle
Needle Actuation :
The needles can be moved with single valve gate nozzles and in multiple nozzle and manifold systems with
* single needle valve
* lifting plate
* sliding plate mechanism
and can be designed for pneumatic or hydraulic operation.
Special holes in the mould clamping plate allow the depth of the shut-off needles to be adjusted individually from the outside. The choice of needle actuation depends on the application, the available space and the size of the mould.
