I. Core Structural Features
- Connection and Sealing :Left end external thread, right end internal thread, thread conforms to 《GB/T 7306 55° sealing pipe thread》; built-in nitrile rubber sealing gasket (conforms to 《GB/T 5574 Industrial vulcanized rubber sheet》), forming a double seal with the valve core soft seal (conforms to 《GB/T 12237 Industrial valves metal sealed ball valves》) Double Seal ,Reinforces gas medium airtightness.
- Operating Mechanism :Red engineering plastic handle (conforms to 《GB/T 1040 Determination of tensile properties of plastics》), 90° rotation opening and closing, handle and stem are non-detachable, small operating torque and intuitive opening and closing status (handle parallel/perpendicular to flow direction corresponds to opening and closing).
- Valve Body Material :The main body uses brass material (conforms to 《GB/T 5231 Chemical composition and product shapes of processed copper and copper alloys》), suitable for gas, compressed air and other non-corrosive gas environments.

V. Typical Application Scenarios
- Domestic Gas System :Natural gas, liquefied gas household branch pipes, gas stove/water heater front-end pipeline control (must comply with local gas safety regulations);
- Industrial Gas Transportation :Opening and closing of compressed air, nitrogen, argon and other inert gas pipelines (suitable for pneumatic equipment, gas station houses);
- Pneumatic Equipment Matching :Gas source switch for pneumatic tools, cylinders and other pneumatic components, facilitating equipment maintenance and gas volume adjustment;
- Laboratory Gas Path :Precise control of gaseous media for analytical instruments and experimental devices (suitable for small and medium-sized precision scenarios);
- Small Gas Appliances :Gas supply pipeline for gas boilers and burners (gasket seal enhances airtightness).
