This device is used to reduce the purge gas flow rate in some processes, Used with pumps equipped with purge valve, Flow reduction to 50 sccm

Purge valve kit for ATH 500 M only (not used for MT version), The valve is driven by the customer, Driven by 24 V DC signal

The gas purge provides protection to the pump bearing, Recommended for corrosive applications, The purge of this valve may be isolated during an air tightness test, 50 sccm
