I. Core Structural Features
- Connection Type :The left end of the valve body is a male threaded interface 、and the right end is a female threaded interface ,both threads conform to the standard of GB/T 7306 55° sealing pipe thread, suitable for various gas pipeline hard pipe connections;
- Sealing Structure :The valve core and valve seat adopt a soft sealing design (in accordance with GB/T 12237 Industrial Valves Metal Sealed Ball Valves), with a nitrile rubber sealing component to enhance the airtightness of the gaseous medium;
- Operating Mechanism :Equipped with a red reinforced nylon handle (in accordance with GB/T 1040 Determination of Tensile Properties of Plastics), 90° rotation completes opening and closing, the handle and stem are anti-detachment connected, the operating torque is small and the opening and closing status is intuitive (the handle is parallel/perpendicular to the flow direction corresponding to opening and closing);
- Valve Body Material :The main body uses brass material (in accordance with GB/T 12225 General Valves Copper Alloy Castings Technical Conditions), 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 stations);
- Pneumatic Equipment Matching :Gas source switch for pneumatic tools, cylinders and other pneumatic components, convenient for equipment maintenance and gas volume adjustment;
- Laboratory Gas Pipeline :Precise control of gaseous media for analytical instruments and experimental devices (suitable for small and medium-sized precision scenarios);
- Small gas equipment Gas supply lines for gas boilers and burners (soft seal enhanced airtightness).
