• Maintains Accurate Settings: The minimum setting available is 1.25 psig. Maximum pressure setting is 15 psig. All vents are tested to Valve Concepts, Inc. high standard
  for leakage and set point prior to shipment. A certified test certificate is included with each vent verifying the accuracy. A leakage rate of less than 1 SCFH at 90% of customer specified set point is verified
• Drenagem de condensado: O corpo da carcaça com drenagem automática e os anéis de gotejamento mantêm o condensado longe das superfícies de assentamento, evitando o congelamento, a aglutinação e o entupimento.
• Assento com almofada de ar: O assento com colchão de ar proporciona vedação firme para reduzir as perdas por evaporação. Os paletes têm uma guia externa e uma haste estabilizadora central para proporcionar autoalinhamento e encaixe firme.

Técnica

A spring loaded pallet allows for the discharge of vapors to the outlet piping when the tank pressure exceeds the pressure set point. Once the tank over pressure is relieved the spring loaded pallet closes providing a tight vapor seal. A flanged outlet connection is provided for easy pipe-away of vapors, eliminating their emission into the atmosphere and allowing compliance with applicable regulations.
