It is a safety valve that protects the tank from damage caused by positive and negative pressure.
Our company offers the 'Model 707 Breather Valve', which is suitable for chemical tanks made of FRP or polyethylene, as well as stainless steel storage tanks, due to its lightweight and rust-free properties. During the injection and discharge of liquids into the tank, as well as due to the expansion and contraction of air or gas caused by temperature changes, the valve automatically regulates the pressure inside the tank to maintain it at normal levels and prevent damage. It is particularly used for chemical tanks containing hydrochloric acid, sulfuric acid, nitric acid, sodium hypochlorite, caustic soda, PAC, sulfuric acid bands, and ferrous chloride, among others. 【Specifications】 ■ Connection & Size - PVC/PP Flanged type: 25 to 100A ■ Operating Pressure - Please specify within the range of +30 to +300 mmAq and -30 to -100 mmAq *For safety, it will be set to operate earlier than the specified pressure. *For more details, please download the PDF or feel free to contact us.
