Valve gate control -NVS

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.

  1. Hot runner controller
  2. Visualitation
  3. Needle Valve Control System

Device rear view:


Two standard Ethernet connections secure the connection to the hot runner controller as well as to the external application.


  1. Solenoid valve connection
  2. Power supply
  3. Way sensor connection
  4. Controlling signals of the machine
  5. 2 x Ethernet connection

Possible combinations:


All device data and mould settings can be centrally stored and managed via the Ethernet connection. Furthermore, additional devices such as needle valve-control NVS and pressure measuring system DMS are linked with the devices via the Ethernet connection. These then perform the operation and visualisation. Various injection moulding machines can be connected via conventional data interfaces or via the Ethernet so that operation and visualisation occurs on the machine’s screen.
