PEV volumetric sampling valve – Definox

PEV volumetric sampling valve integrate a physical barrier between the interior of the valve and the external environment. The sample is taken under optimum aseptic conditions.

In order to facilitate powder sampling from drying silos, Definox offers a volumetric sampling valve. The powder flow is gravity discharged. It allows for repeatability of the sample taken from a given volume or frequency.

Features
