FlowTherm presents the PEVL volumetric sampling valve, used to sample automatically and sequentially a sample of constant volume of clear or low viscosity liquid on a transfer line. The PEVL has pneumatic control and is equipped with a sampling chamber, a sampling piston and a drive cylinder. With each movement of the drive cylinder, the sampling piston samples the product in the transfer line corresponding to the volume trapped in the calibrated neck of the piston. When the piston returns to its initial position, the sample is transferred to the sample vessel via the outlet tube. The sampling chamber is cleaned by connecting the valve to the CIP installation or by injecting a sterilising liquid.

Benefits:

• Sampling of a constant volume at regular intervals (automatic)
• Hygienic design, with the possibility of mounting a cleaning valve in line
• Sampling volume factory calibrated, from 1 ml to 40 ml
• Possibility of undertaking up to 600 samples per hour
• Easy maintenance due to the presence of a single membrane
• Sterilisation by SIP/CIP circulation

Applications:

• Sampling on the transfer line of a clear or low viscosity liquid
• Equipment especially suited to sampling of products subject to quality and/or bacterial controls
