Butterfly valves have been on the market for many years, and over the years, there have been improvements and adjustments in order to meet the daily needs and demands of industries in different segments.
The changes have been made mainly due to security issues, which is an operational priority of every industry process regardless of the business sector.
There has been a noticeable increase in environmental and occupational safety regulatory requirements. Especially when it comes to fires in places that have flammable fluids, it is essential to use valves that meet this need and these valves are called Fire-Safe Butterfly Valves.

Let's get to know a little more about how Fire-Safe Butterfly Valves work (fireproof) and their importance!

Do you know what a butterfly valve with Fire-Safe requirement is?
When a valve is able to maintain the fluid sealing property of its seat, packing and body, even when exposed to a fire, it is considered a fireproof or fire-safe valve.

How important is this requirement in a butterfly valve?
With this requirement, the fluid passing through the pipeline and being contained by the valve, even though it is flammable, will not leak to feed and make the fire worse. This is essential for the industrial sector safety, life and environmental preservation as well as the protection of the equipment itself. 

How does the valve meet this requirement?
Valves are certified when subjected to laboratory testing with guidelines and criteria in accordance with ISO 10497 and API 607 ​​standards.

Which segments use and benefit from the Fire-Safe Butterfly Valve the most?
Petrochemical and Oil and Gas.
