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 manufacturing of PE separators predominantly utilizes high-density polyethylene (HDPE) incorporating a porous configuration developed through methodologies such as melt-blown extrusion or tensile stretching. The material selection emphasizes its chemical passivity, ensuring it maintains non-reactivity with the battery’s electrolyte medium (commonly sulfuric acid in lead-acid battery systems) and active electrode materials. AGM separators are structured from ultrafine fiberglass filaments (silica-based glass fiber compositions) compressed into a mat-like framework. These fibers undergo specialized surface modification to optimize hydrophilicity and adsorption capabilities, enabling the mat to immobilize the electrolyte in a gelatinous state.
AGM battery exhaust safety valve Pressure Regulation – Prevents excessive internal pressure that could cause swelling or rupture. Recombinant Gas Management – Allows controlled venting while minimizing water loss. One-Way Venting – Releases gas but prevents air ingress, maintaining battery integrity. Flame Arresting – Some designs include flame-resistant materials to prevent external ignition.
AGM battery exhaust valve, Battery exhaust valve, AGM exhaust valve, Exhaust valve, AGM Vent plug Our company produces AGM batteries with a patented design of separating the valve body and valve core assembly. The valve core assembly consists of a valve core, a valve core seat and a limit card. Since it uses high-molecular PC material, the shrinkage rate is very small, the matching accuracy is high, and it is less affected by temperature. It can be used normally in a working environment of -40℃-120℃, and the opening and closing valve pressure consistency is good, and the leakage rate is lower. The valve body is made of engineering-grade PP and injection-molded rubber through a multi-component injection molding machine. The product has a variety of appearances and better sealing performance.
AGM battery Start-stop vent plug, Start-stop vent plug, AGM battery Start-stop safety valve, Start-stop vent plug Our AGM Battery Start-stop Vent Plug is specially designed for start-stop vehicles, ensuring safe and efficient pressure regulation within the battery，meeting the demanding requirements of modern start-stop battery technology, where frequent cycling and high-pressure conditions demand superior reliability.
