The preventive protection system against fire and explosions should give an early indication and immediately extinguish glowing particles, sparks or flames so that fires or dust explosions do not arise.

The choice of extinguishing agent is generally determined by the products handled in the process. Another factor is the availability of an extinguishing agent.

If steam is available, this is a very good extinguishing agent for many applications.

Firefly Steam valve type SV/PS is available for steam pressure from 10 to 69 bar. The valve consists of a quickopening ball valve with a spring tensioned pneumatic controller. The valve has a free bore and comes in dimensions from DN 1 5 to DN80. As standard the valves come with 150 mm welding ends but can also be supplied with flanges.
