What is an explosion-proof fire butterfly valve?
An explosion-proof fire butterfly valve is a specialized valve designed to operate safely in hazardous environments where flammable gases, vapors, or dust may be present. It combines fire-safe and explosion-proof features to prevent ignition risks while maintaining reliable shutoff during emergencies.
Key Features:
Explosion-Proof Certification: Complies with ATEX, IECEx, or NEC (Class I, II, III, Division 1/2) standards, ensuring no sparks or excessive heat are generated.
Fire-Safe Design: Meets API 607/ISO 10497 standards, maintaining sealing integrity even under extreme heat.
Robust Construction: Made of stainless steel, ductile iron, or coated alloys to resist corrosion and mechanical stress.
Special Actuation: Uses explosion-proof electric/pneumatic actuators for safe remote operation in hazardous zones.
Applications:
Oil & gas refineries
Chemical processing plants
Mining & grain storage facilities
Offshore platforms & petrochemical pipelines
