197 ENP END OF LINE DEFLAGRATION PRESSURE VACCUM VALVE

Product catalog summary
Overview: The document describes a Pressure Vacuum Valve with a ribbon coil, which serves as a protection system and end-of-line flame arrester. It complies with Directive 2014/34/EU and the harmonized standard EN ISO 16852:2016. The valve is designed for use in chemical, petrochemical, and pharmaceutical industries to regulate tank pressure, reduce evaporation, and protect against external fires.
Specifications: The valve is available in various models and materials, including aluminum, PTFE-coated, and stainless steel. It is suitable for different gases and vapors, classified under Explosion Group "IIB3" for gases with MESG ≥ 0.65 mm and "IIC" for hydrogen and gases with MESG < 0.5 mm. The maximum operational temperature is 60°C.
Installation and Compatibility: The valve is intended for vertical installation at the end of vapor pipelines. It is NPT threaded and requires specific adaptors for different pipeline sizes. The aluminum model is suitable for traditional fuels, the PTFE-coated model for special fuels and non-aggressive chemicals, and the stainless steel model for aggressive solvents and acids.
Maintenance: Regular checks are necessary to ensure cleanliness and functionality. The product must be replaced after exposure to fire or deflagration. Tampering voids the warranty and compromises safety.
Certification and Compliance: The product is certified and conforms to relevant standards. Documentation, including the Declaration of Conformity and User Manuals, is available online.
Additional Information: Custom applications and maintenance inquiries can be directed to the technical department via email. The document also notes that data and images are not binding and subject to change without notice.
