Era Technologies is Prime Indian Manufacturer & Exporter of Erardo Make Pressure Vacuum relief valves Breather valve is special designed for tank protection The range includes pressure only vacuum only and combined pressure vacuum valves all available with Flanged outlets or vented to atmosphere

Our world wide Presence in Malaysia, Singapore, Indonesia, Thailand, Vietnam, UAE, Saudi Arabia, Oman, Kuwait, Iran, Egypt, Yemen, Qatar, Bahrain, Turkey, Libya, Iraq, Syria, Algeria, Vietnam, Venezuela, Chile, Colombia, Nigeria, Kenya

Pressure vacuum relief valve is used extensively on bulk storage tanks including fixed roof with floating covers to minimize evaporation loss The valves prevent the build up of excessive pressure or vacuum which can unbalance the system or damage the storage vessel

Storage tanks other vessels containing flammable and explosive chemicals and mixture are prevalent in chemical process industries plants Flame Arrester are installed with Breather Valve to prevent potential hazard associated with flammable and explosives materials

Special Features

  • Design of Breather Valve with integrated Flame Arrester such that it gives Maximum Flow low pressure Drop Fire Safe Flame Element size will be 15 times than BV Size It will nullify pressure drop which will occur due to Flame Element
  • Easy cleaning less clogging and less Maintenance Cleaning can be done by removing Wing Nut
  • Flouropolymer coated Body and hardware are provided for outstanding corrosion and chemical resistance
  • Low BlowDown
  • Low Leakage and reduced vapor loss
  • Dead Weight design such that set PressureVacumm can be changed as per need
  • Vacuum port area 1 dot 3 times higher than PV size By this we increased in breathing flow by 30 of required flow
Model No BVFAD
  • Pressure Vacuum side Flame Element Dia 1 dot 5 times of breather Valve Size Hence there is no Flow restriction and Pressure Drop
  • Both side Flame Element are installed at outer side of Breather Valve Hence Maintenance and cleaning will be easy
  • There will be no direct contact with Vapors because of this the life of Flame element increase
  • There will be no blocking as Flame element contact with vapors at the time of Pressure condition
  • During Fire the Flame element directly contact with Flame Hence Tank will be Safe in Fire or explosion
