Product Description

Pilot Operated Breather Valve With Flame Arrestor
 

Breathing valve produced by our company has simplified structure, ventilation volume, less leakage, corrosion resistance, insulationetc.
The valve adopts polytetrafluoroethylene material, has the advantages of low temperature resistant, anti frost. 
The electrostaticprotection device is provided with a respiratory valve, the valve and the tank to keep the same potential moment

Product Feature:
Breathing valve is a kind of air breather which install on the petrochemical fixed storage tank, in order to avoid tank over the pressure or vacuum making the storage tank destruct, prevent the outside flame enter, reduce the tank fluid volatile.

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.
