Flanged Breather Valve

The flanged breather valve is most common type of the breather valve, we still have the thread type breather valve. Breather valve always used together with the flame arresting.

Our company engaged in petrochemical industry warehousing and transportation speciality of device fabrication produce the house, it is a specially-designated factory of Ministry of Chemical Industry, and obtained key recommendation of Ministry of Construction of the project of Chinese Petro-Chemical Corporation.

Over pressure and vacuum protection with compact dimensions for extremely low pressure ranges from ±2 mbarg.

2. Reliable leak-tight seal.

3. Pressure setting can be subsequently changed.

4. Suitable for applications with corrosive atmospheres due to corrosion-resistant E-CTFE and PFA coating.

5. Quick and easy to install and service.

6. Reduces nitrogen requirements to a minimum for inerted processes.

7. Ideal for applications with high product purity and quality assurance requirements.

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.
