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
Needle valve-control – all in one mould data record
Ahead of the competition: Data visualisable via hot runner controller
Part of our range since 2017 The needle shut-off- control system 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 shut off 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.
