Suitable for sampling chemicals that are both highly corrosive and highly reactive, the PFA-coated PNI sampling valve with nitrogen rinsing enables representative sampling to be conducted easily and safely without interrupting manufacturing processes. It is designed to be installed on a horizontal line. 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. The PNI's one-piece design reduces dead zones and ensures a perfect sealing. Initially manufactured in stainless steel with a pure PFA coating, it is also available in antistatic PFA to meet specific requirements. Its ingenious quick connection system makes it possible to use different bottles and accessories without changing the sampling system. It facilitates management while limiting costs. Based on a modular concept (spindles, actuators), the PLI sampling system, also known as PRISEMASSON®, can be adapted to meet a wide range of needs and requirements. This sampling system offers significant advantages in terms of performance and cost.
