PROTEGO®
Pressure and Vacuum Relief Valves with Flame Arrester

Reliable tank protection with controlled venting and explosion protection
Pressure and Vacuum Vacuum Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. Relief Valves with integrated Flame Arrester Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. Unit combine two critical safety functions into a single unit: controlled tank breathing and protection against flame transmission. This configuration is widely used in storage tank systems handling flammable vapours, where both pressure and vacuum protection and ignition risk must be addressed in a compact, engineered solution.

Lorem Ipsum Zero Emissions with PROTEGO® Breather Valves
Lorem IpsumThe extreme tightness of PROTEGO® Valves guarantees Zero Emission at Tank Operating Pressure.
Due to the highly developed manufacturing technology of PROTEGO® valves the tank pressure Tank pressure Tank pressure is the pressure within a tank. is maintained up to set pressure Set pressure Set pressure is the gauge pressure at the device inlet at which the relief device is set to start opening under service conditions. with a tightness that is far superior to the conventional standard. According to the PROTEGO® Standard PS-001 leak rates are measured at 90% of the set pressure. This testing ensures PROTEGO® Valves exceed the most stringent leakage rate requirements of EPA, API2000 and EN ISO 28300.

Overpressure refers to an increase in pressure in a system or vessel above the normal operating pressure.
technology. This technology provides very short opening and closing pressure ranges. The vent only requires 10% overpressure above the set pressure to reach full performance. The tank pressure is maintained up to just below the maximum permissible tank pressure.
PROTEGO® 10% full-lift technology vents are a major benefit to emission reduction and to safe process plant operation.
The devices have performed as promised with low leak rates and minimal maintenance effort. We highly recommend them.
