Features

• Modular Design: The Model 3600 end-of-line conservation breather vent is part of Valve Concepts, Inc. modular vent product line. The Model 3600 can easily be field converted to a pressure only vent, a pressure/vacuum vent with pipe away and can either be direct acting or pilot operated. Only Valve Concepts offers complete modularity throughout its complete vent product line.
• Maintains Accurate Settings:Minimum setting available is approximately 0.25 oz/in2 and maximum setting upwards to 2.5 psig. See Set Point Limits Tables 4(a) and 4(b). If higher settings are required, see Valve Concets Series 4000 Spring Loaded Vents. All vents are tested to Valve Concepts, Inc. high standards for both seat leakage and set point prior to shipment. A certified test
  certificate is included with each vent verifying the accuracy of vacuum setting and seat leakage. Seat leakage rates meet or exced current editions of API Standard 2000.
• Drenagem de condensado: O corpo autodrenante e o anel de assento especialmente projetado mantêm o condensado longe das superfícies de assentamento, evitando o congelamento, a aglutinação e o entupimento.
• Assento com almofada de ar: O assento com almofada de ar proporciona uma vedação firme para reduzir as perdas por evaporação e a liberação de vapores tóxicos. Os paletes têm uma guia externa e uma haste estabilizadora central para proporcionar autoalinhamento e encaixe firme.

Técnica

Weight loaded pallets in the vent housing allow the intake of air and the escape of vapors as the tank breathes due to thermal changes and product movement out of the tank. The pallet opens and closes to permit in breathing necessary to maintain tank pressure and prevent tank damage due to excessive vacuum.
