Explosion-Proof Valve
Product Overview
Product OverviewThe Explosion-Proof Valve is specially designed to ensure safe, stable, and certified control of gases and liquids in flammable, explosive, or dust-prone environments. It plays a vital role in preventing fire and explosion risks by isolating any potential ignition sources within its fully sealed structure. Manufactured by Vcore Valves, this product is constructed using flameproof-grade materials such as carbon steel and stainless steel and features certified explosion-proof electric or pneumatic actuators. It is widely applied in chemical plants, oil refineries, paint production, grain processing plants, and gas networks—where safe operation is not optional but mandatory.
Key Features:
Certified for hazardous environments (ATEX, IECEx, CNEX); explosion-proof electric or pneumatic actuator with sealed ignition chamber; anti-spark structure and static-proof internal components; full-port design allows reliable flow with minimal pressure drop; high-integrity sealing for zero leakage; long lifecycle and reduced maintenance.
