Suitable for sampling chemicals that are both highly corrosive and highly reactive, the PFA-coated ENP sampling valve (without flange) with nitrogen rinsing enables representative sampling to be carried out 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 ENP'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. The wafer design without flange reduces pressure losses and space requirements. Its ingenious, robust bayonet 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, the ENP sampling system, also known as PRISEMASSON®, can be adapted to suit different needs and requirements. This sampling system offers significant advantages in terms of performance and cost.
