Air Nozzle / Inflation Valve

I. Core Product Values

• Ensure inflation efficiency and operational safety, enabling fast inflation and long‑term sealing.
• Provide stable operation with smooth press‑on/off and consistent spring return response.
• Improve reliability over product life cycle, free from jamming or rusting in long‑term use.
• Reduce assembly and usage risks, easy to install without damaging seals or piping systems.

II. Custom R&D and Quality Control Key Points

(1) Sealing Performance (Core Quality Requirement)

• Strictly control geometric tolerances such as flatness and circularity of the valve core sealing surface.
• Guarantee dimensional and geometric accuracy of O‑ring and seal installation grooves.
• Implement full‑process air tightness testing to eliminate air leakage risks.

(2) Inflation Efficiency and Fluid Performance

• Take inner bore diameter as the core design parameter for inflation speed.
• Optimize flow passage design with smooth inner walls, no necking, and no fluid dead zones.

(3) Structural Durability and Stability

• Spring fatigue life and resilience meet long‑term high‑frequency usage requirements.
• Stable movement of valve core, free from jamming or deflection.
• Connection structures including quick‑connect, thread, and buckle meet strength standards and adapt to working conditions.

(4) Assembly and Usage Protection Design

• Precision treatment such as inner bore chamfering and deburring.
• Structurally prevent damage to matching components including O‑rings, airbags, and hoses.

III. Application Coverage and Industry Adaptation

• Tire applications: passenger vehicles, electric vehicles, bicycles, engineering vehicles
• Inflatable products: air mattresses, toys, airbags, inflatable models
• Pneumatic systems: air cylinders, gas springs, various inflation tools
• Medical equipment: breathing balloons, pressure gauges, anesthesia machines and other precision devices

IV. Material Selection Logic (Matched by Application Scenarios)

• General cost‑effective: H59/H62 Brass — excellent air tightness, good machinability
• Anti‑corrosion & durable: 304 Stainless Steel — strong rust resistance, long service life
• Lightweight demand: Aluminum Alloy — light weight, suitable for portable products
• Food & medical grade: 316L Stainless Steel — high corrosion resistance, good biocompatibility
