All-Weather Breathing Valve With Flame Arrester
Breathing valve is to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use ofprinciples of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work.
According the countryGB50160 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（fire-proof）breathing valve whole series。Withing scientific and smart mould、completely specific-ation 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 suc-tion、exhaust connection nozzle, also can manufacture any different material according to different medium such as petroleum、chemical、food industry,totally satisfy ev-ery kinds storage system process requirements.
