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.
> provide safety by preventing the release of toxic gas or corrosive gases into the workplace when changing cylinders
> provide corrosion resistance by preventing corrosive or halogen gases from coming into contact with atmospheric moisture
> maintain purity by preventing air from infiltrating high purity systems at the time of cylinder change.
Chem- Master Regulator Purge Valves:
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.
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.
