Description

BZSV ZHII Flame Arrester – 2" to 12", ANSI 150LB RF, Anti-Explosion Type

The BZSV ZHII Flame Arrester is a subsonic-speed anti-explosion safety device engineered for installation at the ends of vent pipelines or the top of live vertical storage tanks. Designed to prevent flame propagation through vapor lines, it serves as a reliable safeguard against flashback in facilities storing flammable liquids. This unit is optimized for Class A (flash point < 28°C) and Class B (flash point < 60°C) volatile hydrocarbons such as gasoline, toluene, crude oil, and kerosene.

Constructed for use in low-pressure systems (≤ 1.0 MPa), the ZHII arrester integrates seamlessly with compatible breathing valves for combined pressure/vacuum relief and flame arresting. Its design ensures the fire element remains secure and effective under pressure, delivering both passive explosion prevention and durable mechanical protection.
