Brief Introduction

The Explosion-proof Vacuum Conveying Safety Valve is a critical safety device specifically designed for vacuum conveying systems in explosive environments. Manufactured using explosion-proof certified materials, it integrates pressure release and vacuum maintenance functions to effectively control explosion risks and pressure abnormalities during powder conveying processes. The safety valve features a special bursting disc design and spring-loaded mechanism, enabling immediate activation when pressure exceeds preset values for effective pressure relief and system integrity protection.

The valve body is cast from 316 stainless steel, with internal explosion-proof components certified by ATEX/IECEx. It operates within a temperature range of -40°C to +150°C, with bursting pressure accuracy reaching ±5%. The unique bellows structure ensures rapid pressure release while maintaining vacuum, and the anti-static design effectively prevents electrostatic accumulation, making it suitable for combustible dust environments.
