Product Description

MATHESON made in the USA

 

 

Matheson's 4774 Series Cross Purge assembly which contains a vent, isolation, and purge gas valve is highly recommended when using toxic or corrosive gases and is also intended for use with high purity applications where preventing contaminates such as air and water vapor is critical.   Atmospheric contaminants become trapped in the high pressure portion of the regulator upon connection to another cylinder. If allowed to remain they are swept into your system.  Depending upon your flow rate and desired purity level, these impurities can disrupt your process for days or even weeks.  Purging with an inert gas will also remove residual toxic or corrosive gases before changing out cylinders.

Dry nitrogen or clean dry air needs to be supplied to the cross purge.

The 4774 Cross Purge has a 1/4" NPT-Male fitting on the outlet.

Cross purges are typically bought already installed on a pressure regulator.
