Defusion Resistant Regulators 

HMP offers a comprehensive range of diffusion resistant, non-contaminating, all metal pressure regulators. These are specially designed and manufactured to ensure diffusion resistance and to handle safely a wide variety of high purity gases, calibration gases, toxic and corrosive gases.

The selection of a suitable pressure regulator involves many criteria including the need for preventing diffusion,compatibilty of material, pressure and flow ratings,safety requirements and so on. HMP makes two type of regulators single stage and two stage, made of stainless steel (SS 304, SS 316) and brass with SS diaphragm.Hmp pressure gauges are also made of stainless steel with SS burdon tubes.

These regulators find application wherever the integrity of gases has to be maintained. Applications include high purity gas line, chromatographic carrier gas supplies, standard gases for calibration of analytical instruments, electronic / semiconductor grade gases and gases which are toxic / reactive / corrosive.
