Fiege electronic

Needle valve-control – all in one mould data record

Let’s start with the main features:

  • compact add-on device as “NVS” or as stand-alone version “NVS-TP”
  • for 4 to 32 zones in steps of 4
  • 24V DC control mechanism
  • Operation via hot runner controllers or via the touch display on the front (NVS-TP)
  • Flexible visualisation

Ahead of the competition - It’s your choice:

One of the most recent Fiege electronic top performers is the stand-alone version of the proven needle shut off control of the NVS series. The NVS-TP version has its own touch display and can therefore be used completely independently of the hot runner controller. The proven NVS version extends any existing temperature controller (software version 3.0 and above) by the functionality of a needle shut off control. With this development, Fiege yet again sets the standard in terms of flexibility and ease of operation. The devices of the NVS series can be used irrespective of the hot runner manufacturer.
