Braunschweiger Flammenfilter - Low Pressure Vacuum Relief Valves and Flame Arresters

Braunschweiger Flammenfilter, international Trademark PROTEGO and Flamefilter, specialises in the production of low pressure safety relief valves and flame arresters for the chemicals industry.

Braunschweiger's range of low pressure safety valves includes pressure and vacuum relief valves, combined pressure / vacuum relief valves and user-operated pressure relief valves.

Our valves are designed to relieve excess pressure or vacuum that remains tightly closed up to set pressures that are not covered by standard safety relief valves. Our low pressure safety relief valves meet the same quality requirements expected of standard safety valves. As an environmentally aware company, we strive to ensure high pretension of valve sealing.

We also manufacture flame arresters for use in many industrial applications. Engineered for explosion protection, our flame filters are widely recognised as amongst the safest on the market. The wide range of deflagration and detonation flame arresters feature maintenance-friendly design and optimized performance.

END-OF-LINE PRESSURE / VACUUM BREATHER VALVES

We supply a broad range of end-of-line pressure / vacuum breather valves for industrial chemicals applications.

The vacuum relief valves and pressure / vacuum relief valves both feature end-of-line deflagration flame arresters.

Braunschweiger's pressure relief valve end-of-line flame arresters feature the unique 10% technology valve with pallets and guide elements that are designed in accordance with the set pressure-range.

Proof against deflagration and endurance burning, our pressure relief valves operate at a set pressure from 3,5mbar up to 200mbar. It has received Explosion group IIA and IIB3 (NEC group D and C) approval.
