PROTEGO®
Breather Valves

Reduction of Vapour Emissions & Safe Plant Operation
In closed containers or tanks, controlling pressure is crucial. PROTEGO® Pressure and Vacuum Relief Valves ensure safe operations by managing accumulated pressure and compensating for vacuum conditions.
Optimized for scenarios like loading, unloading, clean in place, and thermal effects, PROTEGO® Conservation Vents function as pressure relief, vacuum relief, or combined valves. Trusted by industries such as oil and gas, chemical, pharmaceutical, and bio-energy, PROTEGO® Valves ensure safety and efficiency with innovative design and superior performance.

Highlights of PROTEGO® Breather Valves
Minimum Emissions with PROTEGO® Breather Valves
The extreme tightness of PROTEGO® Valves allows for Zero Emission at Tank Operating Pressure.
Due to the highly developed manufacturing technology of PROTEGO® Conservation Vents the tank pressure is maintained up to set pressure 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.
To meet the goal of emission reduction, PROTEGO® full lift vents utilize 10% overpressure 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, reducing valve opening and closing cycle frequency and therefore optimizing tank venting performance.
PROTEGO® 10% full-lift technology vents are a major benefit to emission reduction and to safe process plant operation.
The pressure vacuum relief valves which you have manufactured and delivered have ensured that we have highest level of safety at our facility and at the same time minimised emissions - therefor saving us a considerable amount of money from lost product.
