Designed for vertical lines, the VLN spindle valve with nitrogen rinsing option enables representative sampling to be carried out easily and safely, without interrupting production processes. Nitrogen rinsing through the spindle plays an essential role in inertising and cleaning the bottle, preventing undesirable reactions and eliminating the risk of explosion or ignition, while preserving the purity of the sample. Its ingenious quick connection sampling system allows a variety of bottles and accessories to be used without having to replace the sampling system, simplifying management while keeping costs under control. Initially manufactured in stainless steel with PTFE sealing, it is also available in other alloys and seals, depending on specific needs. Based on a modular concept (materials, sealing, actuators, connections), the VLN sampling system, also known as PRISEMASSON®, can be adapted to suit different needs and requirements.
