C.I.E. manufacture a wide range of BREATHER VALVES for use in various chemical/process industries for all sorts of application in design to prevent vapor losses by evaporation in storage containing volatile liquids and to safeguard the vessel in vacuum/pressure condition. During vacuum it breathes the air/gas inside the vessel and protects the external pressure. When the vessel is loaded, the gas pressure is built up. The pressure port which is set to open discharges the excess gas through the venting line. The general materials are C.I., CAST STEEL, STAINLESS STEEL, SS-304/316, ALLOY-20 and any other material as per client's requirements.
