In many cases, reliable fire protection is essential for industrial valves. Finally, they are responsible for safety in tough applications, for example in the oil and gas industry or in the chemical and petrochemical industry. They must guarantee a reliable and safe shut-off in case of fire. This has now been certified by the TÜV SÜD with the Fire Safe Approval for the E Series Valves and Manifolds of AS-Schneider. Through the independent testing, AS-Schneider can now offer the E Series as "Fire Safe Certified" – a significant advantage over solutions that have only been awarded the "Fire Safe Design". These products are also designed to operate in case of fire, but have not been officially tested. The approval applies to both the Standard Valve Head Units of the instrumentation range as well as for the OS&Y Design. In this version belleville washers are used which compensate for the linear expansion of the individual components and thus provide more reliability at the primary shut off.
