Chem-tech engineering works offers a wide range of breather valves for use in various chemical and process industries for all sorts of application and design to prevent vapour losses by evaporation in storage containing volatile liquids and to safeguard the vessel in vacuum/pressure condition. During a vacuum these valves breathe the air/gas inside the vessel and protects the external pressure. The sizes range from 1/2" to 2" in screwed and 1/2" to 12" in flanged connection. General materials of construction are ci, cs, ss-304/316, alloy-20 and other materials as per customer`s requirements.
