Tank inner ventilation device yac en

The YAK EN pressure / vacuum vent is designed to ensure the breathing of tank compartments. carrying hydrocarbons. This version ensures the durability of the design and regulatory tests of tank vehicles. It is in compliance with the regulations in force for the transport of hazardous materials. It is approved according to EN 14595 (october 2016), contributes to the protection of the environment in case of pouring or overturning of the tank. It prevents the internal pressure from reaching an abnormal value. It allows unloading operations, and is designed to ensure the equipotentiality of the masses. Characteristics: Service function at normal pressure. The gases resulting from the evaporation of the product are evacuated by the pressure valve tared at: 10 (0 / -2) kPa <=> 100 (0 / -20) mbar Service function during unloading: the vacuum valve allowing the entry of air into the compartment during unloading is calibrated at 1 + where- 0,2kPa (10 + or -2mbar) service function when reversing: the device comprises a shut-off valve closing the evacuation passage of the service function normal when the inclination of the tank reaches 90 °. Construction: - aluminum alloy body - flame screen: stainless steel - springs: stainless steel - Seals: fluorinated elastomer VITON
