Vacuum Breather Valve

We have two models of the breathing valves, Type 89 Breathing valve and the Type 89 flame arrester breathing valve. Those two kind of the breather valve is improved from the normal breather valves, we adjust the performance and technical, which will make the breathing valves more stable, the applicable conditions are more extensive, especially suitable for the areas which have very bad climates.

The flame arrester breathing valve is a ventilation device installed on the fixed roof tank, which can reduce the evaporation loss of oil products, control the tank pressure and prevent the introduction of external flame.

The valve has the characteristics of large ventilation, small leakage, corrosion resistance, etc., and has static grounding wire, so that the valve and the tank body maintain equal potential.The valve has antifreeze performance and is suitable for cold areas.

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.

1) The product is reasonable in structure, beautiful in shape and good in corrosion resistance.

2) Polytetrafluoroethylene material is used for valve disc and sealing ring, which has good low temperature resistance and antifreeze performance. Stainless steel material is used for the core of resistance layer, which has strong corrosion resistance, burning resistance, explosion resistance and other technical properties with outstanding advantages.

3) The valve is a ventilation and fire-retardant device installed on the fixed roof tank, which can reduce the evaporation loss of the storage and control the pressure of the storage tank. Its function allows the flammable and explosive gas to prevent the suffocation of the flame.

4) The valve has the characteristics of large ventilation, small leakage, corrosion resistance and good antifreeze.

5) It can adjust the internal and external pressure difference automatically.

6) The fire-retardant layer is easy to repair, clean and install. It is not necessary to disassemble the breather valve during inspection.

7) The water pressure test is qualified.
