I. Core Structural Features
- Connection Type : Both ends of the valve body use internal threaded connection , the thread conforms to the standard of GB/T 7306 55° sealing pipe thread, with strong adaptability and convenient installation, easy to integrate into various pipeline systems;
- Sealing Structure : The valve core and valve seat use soft sealing design , the sealing performance meets the requirements of GB/T 12237 Industrial Valves Metal Sealed Ball Valves, ensuring low leakage;
- Operating Mechanism : Equipped with long handle , the handle and stem use a non-detachable connection design, 90° rotation can complete opening and closing, the operating torque is small and the opening and closing status is intuitive (the handle is parallel/perpendicular to the flow direction corresponds to opening and closing);
- Valve Body Material : The main body uses brass material, the corrosion resistance performance conforms to GB/T 12225 General Valves Copper Alloy Castings Technical Conditions, suitable for water, oil and other non-corrosive fluid environments.
