With double over breathing valve ( With suction, with exhale, fire) Take over breathing valve oil, gasoline, kerosene, aviation oil, light diesel oil, aromatic hydrocarbons, propylene, nitrogen and other fixed roof tank on indispensable main safety equipment, can prevent evaporation loss and protect the tank from damage when the overpressure or vacuum. Take over ( Fire) Breather valve is to maintain tank pressure balance, reduce medium volatile security energy-saving products. To take over the breather valve is installed on the fixed roof tank ventilation and fire equipment, may help to reduce oil product evaporation loss, control the tank pressure balance and control the flame. It can be to automatically adjust the inside and outside the positive pressure and negative pressure storage tank, etc. This series of electrostatic protection device are set to use inside the respiration valve, make the valve time maintain equal potential with the tanks.

with double over breathing valve routine application specification:

1. The flange standard: GB, HG, SH, HGJ, JB, ANSL, JIS and other standards. ( The user to specify, please indicate the pressure level) ;

2。 Manufacturing, testing standard: according to the ( Oil tank breathing Industrial Valves) SY7511 - 87 ( The oil tank flame arrester fire performance and test methods) And GB/T5908 - 2005、GB / T50160 - 2012年,GB / T13347 - 92 and other rules and standards for manufacturing and acceptance; Or the user to specify criteria;

3。 Main material: cast steel, carbon steel, WCB, 316, 316 l stainless steel 304 ss, etc. ;
