Cross Purge AssembliesPurging 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 

Select the model you require:

LPS - Lever operated diaphragm valve1/4 npt m1/4 compDV200Stainless steel

Purge gas inlet via 1/4"compression fitting and check valve in stainless steel.

Vent outlet via 1/4" compression fitting.
