Product Description

MATHESON made in the USA

 

 

Corrosive service regulators constructed of Monel and Elgiloy for superior corrosion resistance.

Applications

• Pressure regulation of acid forming halogen gases, such as hydrogen chloride, chlorine, hydrogen fluoride, hydrogen bromide, and silicon tetrafluoride
• Dispensing of corrosive calibration gases
• Research and development applications where a corrosion resistant regulator is required for either corrosive ambient conditions or corrosive gas service
• Applications requiring extended regulator lifespan in severe conditions.

MATHESON strongly recommends the use of a cross-purge with any regulator put into highly corrosive or toxic gas service. You can easily add a cross-purge to this model regulator by selecting "Yes" for the Cross Purge option above.

Design Features

• Monel and Elgiloy construction for excellent corrosion resistance
• PCTFE seat material for use with chlorinated compounds
• 2-1/2” Monel gauges
• Equipped with Monel needle valve on outlet
• 1/4” NPTM outlet connection
