Regulator Purge Valves
Chem-Master Purge Valves are designed for use with high purity and corrosive gases to ensure system integrity during gas source changes or maintenance and repair.
Purge valves;
>  provide safety by preventing the release of toxic gas or corrosive gases into the workplace when changing cylinders
>Â provide corrosion resistance by preventing corrosive or halogen gases from coming into contact with atmospheric moisture
>Â maintain purity by preventing air from infiltrating high purity systems at the time of cylinder change.
Chem- Master Regulator Purge Valves:
Deep Purge:
The Deep Purge may be used to purge the entire regulator body or just the cylinder connection at the time of cylinder change.  The Deep Purge performs a positive displacement purge of the system.
Through Purge:
The Through Purge is effective in purging the regulator cavity and downstream system. An isolation and vent system is installed downstream from the regulator to direct the vented gases to a safe location.  This type of purge is best suited to pressure cycle or dilution purging.
High Pressure Purge:
The High Pressure Purge connects to a regulator body through the high pressure inlet port. The purge gas is vented through the regulator body to a safe location downstream. This type of purge is best suited to pressure cycles and dilution purging.
**Regulator is not included.
