With double takeover breathing valve (with inhalation, with exhaled, fire retardant) take over the breathing valve Crude oil, gasoline, kerosene, aviation oil, light diesel oil, aromatic hydrocarbons, propylene, nitrogen and other fixed top-type storage tank on the indispensable main safety equipment, Play a role in preventing evaporation loss and protecting the tank from damage caused by overpressure or vacuum. With take over (fire resistance) breathing valve is to maintain the tank pressure balance, reduce the volatile media, energy-saving security products. Take over the breathing valve is installed in the fixed roof cans on the ventilation and fire retardant devices, can play to reduce oil evaporation loss, control the pressure of the tank balance and control the role of the flame. It can automatically adjust the pressure inside and outside the tank and negative pressure automatically. The series of breathing valve with electrostatic protection device, making the valve moment and the tank to maintain the same potential. With double take over the breathing valve routine application specification: 1. Flange standard: GB, HG, SH, HGJ, JB, ANSL, JIS and other standards. (User specified, please specify the pressure level); 2. Manufacturing, testing standards: (oil tank breathing valve) SY7511-87 (flame retardant performance of oil storage tanks and test methods) and GB / T5908-2005, GB / T50160-2012, GB / T13347-92, etc. Regulations and other standards for manufacturing and acceptance; or user-specified standards; 3 main material: cast steel, carbon steel WCB, stainless steel 304SS 316 316L and so on; 4. Nominal pressure: 0.6MPa 1.0MPa. 1.6MPa 2.5MPa American Standard 75LB 150LB. Please specify when ordering: product name, nominal diameter, pressure level, material, flange standards, operating pressure, media and other detailed parameters.
