Needle valve-control – all in one mould data record

Let’s start with the main features:

  • Compact add-on device
  • for 4 to 32 zones in steps of 4
  • 24V DC control mechanism
  • Operation via hot runner control devices
  • Flexible visualisation

Ahead of the competition: Data visualisable via hot runner controller

One of the most recent Fiege electronic top performers is the newly developed needle valve-control of the NVS and NVS plus series. Combined with the temperature controllers of the TP and VARIO series (software version 3 and above), both the needle valve-control and the also newly developed Fiege pressure measurement system can be visualised through an existing hot runner control device. With this development, Fiege yet again sets the standard in terms of ease of operation. NVS is optionally available with end position control and can be used irrespective of the hot runner manufacturer.
