Ayvaz VK-70 Vacuum Breaker

Pipeline and Equipment Protection Solutions

High pressure can occur during the usage of steam installations and devices. However, when the process stops, the remaining steam condenses due to cooling. This volume shrinkage creates an unwanted vacuum inside the pipeline. Ayvaz VK-70 Vacuum Breaker functions like a check valve to prevent damage by pulling air inside as soon as a vacuum starts forming. When steam is re-supplied, this professional Vacuum Breaker closes automatically as the pressure rises. Designed for general-purpose steam or condensate lines, it is a small-sized and reliable Vacuum Breaker option. Manufactured with a durable brass body and robust stainless steel internals, this high-quality Vacuum Breaker must be installed vertically with the connection at the bottom.
