Brass Manifold Valve Base for Inflatable Life Jackets

Manifold Brass Valve Base for Inflatable Life Jackets A full-flow brass valve base with a weldable urethane flange, designed for airtight inflation assemblies in inflatable life jackets and air chambers. Product Description: This manifold brass valve base is designed to support full airflow during inflation, helping deliver stable, consistent air transfer into the buoyancy chamber. The valve base body and valve core are made of brass, offering durability, corrosion resistance, and long service life in marine environments. A weldable urethane (PU) flange is integrated for bonding to most inflatable air chambers / coated fabrics, enabling a reliable airtight joint when welded correctly. The design delivers good gas tightness and stable airflow, making it a key component in inflatable life jacket inflation assemblies. Suitable for OEM production, repair, and spare-part replacement, especially where a robust metal valve base is preferred. Standard reference: EN ISO 12402-7 (Materials & Components) for personal flotation devices—useful as a design/quality reference for components used in compliant lifejacket systems (final compliance depends on the complete lifejacket). Specifications Item Specification Product Type Manifold valve base (inflatable lifejacket accessory) Intended Function Full-flow inflation pathway Body Material Brass Valve Core Material Brass Flange Material Urethane / PU (weldable) Bonding Method High-frequency (RF) heat welding (recommended for coated fabrics) Performance Focus Airtight sealing, stable airflow, long service life Standard Reference EN ISO 12402-7 (component/material requirements reference) Typical Applications Inflatable life jackets / inflatable life vests Inflatable buoyancy chambers and marine safety inflatables OEM assembly lines, maintenance and replacement parts Assembly Instructions Position the valve base on the lifejacket air chamber at the specified mounting location. Use a high-frequency (RF) heat welding machine to weld the urethane flange to the air chamber material and form an airtight bond. After welding, install the manual/automatic inflator onto the valve base thread/interface and tighten securely. Perform an inflation test and leak check before packing, delivery, or service use. FAQ Q1: What does “full airflow during inflation” mean in practice?It means the valve base is designed to allow efficient air transfer into the chamber, helping achieve faster, steadier inflation depending on the inflator and system setup. Q2: Why choose a brass valve base instead of plastic?Brass offers strong mechanical durability and long-term stability for marine environments, which can be beneficial for frequent handling, servicing, and long-life assemblies. Q3: Is the urethane flange compatible with most air chambers?The urethane (PU) flange is intended to be weldable to many coated-fabric air chambers. Actual compatibility depends on the chamber coating/material—sampling and welding trials are recommended. Q4: Does the EN ISO 12402-7 reference mean the part is certified?EN ISO 12402-7 is a design/quality reference for materials and components used in personal flotation devices. Certification/compliance applies to the complete lifejacket system, not a single spare part alone. Q5: What quality checks are recommended after welding?Run a pressure hold/leak test, inspect the weld seam for continuity, and verify the inflator connection is tight and sealed.
