Type VRF. Vacuum valve - ACCESSORIES Indispensable safety factor VETUS has developed this vacuum valve to prevent the tank from imploding in the event of insufficient Aerator, for example when the tank contents are siphoned off from land. The valve complies with the ISO 8099 standard. In the event of a vacuum, the valve opens automatically to feed air into the tank. The use of the valve eliminates the need to install ventilation lines. The valve is made of plastic and is therefore absolutely corrosion-free. Hole size in the tank 56 mm.
