ZFQ-1 series Breathing valve is to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use of principles of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work.

Our breathing valve  has the advantages such as  simplified structure, ventilation volume, less leakage, corrosion resistance, insulation etc.. The  polytetrafluoroethylene material,support the breather valves worked of low temperature resistant, anti frost. 

breather valve is a kind of air breather which install on the petrochemical fixed storage tank, in order to avoid tank over the pressure or over vacuum making the storage tank destruct, prevent the outside flame enter, reduce the tank fluid volatile.
According the country GB50160 stipulate:"A, B kind fluid fixed arch-roof tank, should set arrester and breathing valve". In order to meet the requirement, we develop and exploit all-weather (fireproof)breathing valve whole series. Within scientific and smart mould, completely specification type, compact construction, light weight, huge breath capacity, small leakage etc features. The product construction have breathing type, single exhaust type, single suction type, reducing type, jacket type(detail information please reference HX series breathing valve). Every kind series can mount arrester, also can mount suction, exhaust connection nozzle, also can manufacture any different material according to different medium such as petroleum, chemical, food industry, totally satisfy every kinds storage system process requirements.
