Cross Purge Assemblies

Purging using a cross purge involves sealing off the system at some convenient point and then filling it with a positive pressure of purge gas. The resulting mixture of purge gas and unwanted gas is then vented away (to atmosphere or scrubber).

Repeating the process a number of times produces increasingly dilute amounts of unwanted gas on each cycle. Dilution purging can be improved further by venting the mixture of gas to a vacuum. This vacuum can be produced by a vacuum pump or venturi vacuum generator.

Features

For dilution purging

• Allows purge gas to be introduced to HP part of system
• Allows isolation of regulator and downstream from purging volume, creating a small volume to purge with minimal dead ends
• Available in stainless steel only for use with non corrosive and corrosive gases and the choice of handwheel or lever operated diaphragm valves
