  • CN1807 Internal and External Thread Gas Ball Valve

I. Core Structural Features

  1. 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;
  2. 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;
  3. 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);
  4. 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.
