Material: Valve body: Reinforced nylon or PTFE (chemically inert). Seals: Silicone or Viton® rubber for gas/acid resistance. Pressure membrane: Thin polycarbonate or metal alloy (burst pressure 10–20 psi). Working Principle: Pressure relief: Opens at preset thresholds to vent hydrogen/oxygen gases, preventing explosion during overcharge or thermal runaway. Re-sealing: Closes automatically when pressure normalizes (critical for VRLA batteries)
The Industrial VRLA Battery Safety Valve designed by us is based on Top technology, equipped with acid filter disc and flame arrestor - related process, which filter gas discharged from vent valve and prevents open flame into the valves. As a result, its resistance to acid the flame, water loss and conformance are further improved, thereby extending the service life of the battery. We own the patent over the Industrial VRLA Battery Safety Valve.
lead acid Explosion proof valve,Explosion proof valve The Explosion-proof vent plug is engineered for excellence with a robust construction that guarantees longevity and a premium finish. Featuring a built-in PE filter, it offers superior splash-proof or anti-splash protection, effectively preventing corrosive acid fumes from escaping, thereby averting potential fire hazards and ensuring the battery exterior remains impeccably dry. This crucial feature also safeguards expensive equipment surrounding the battery from damage caused by acid fumes.
