Prevent collapse and damage due to vacuum conditions in pipelines and containers, improving the safety and efficiency of equipment.
We would like to introduce the "Yoshitake Vacuum Relief Valve" that we handle. The vacuum relief valve is a device that controls the flow of liquids, specifically used to prevent backflow in a vacuum state. Typically, when the pressure in a pipeline or container decreases and a vacuum is formed, the vacuum relief valve allows external air to enter to relieve the vacuum. This prevents collapse or damage due to the vacuum state within the pipeline or container, maintaining a normal pressure state and improving the safety and efficiency of the equipment. *It is currently available for sale on the "Plant Navi" wholesale and procurement site exclusively for businesses dealing with plant piping materials and residential equipment operated by Hasegawa Kizai Co., Ltd.
