  • 2002 Inner Thread Single Live Ball Valve

I. Core Structural Features

This product is a 2002 inner thread single live connection ball valve ,The structure conforms to national standards such as "GB/T 12238 Flanges and double-clamp connection ball valves" and "GB/T 7306 55° sealing pipe threads". The core structural features are as follows:
  1. Inner thread + single live connection composite connection :The left side is an inner threaded live connection (conforming to GB/T 7306), which can be rotated to align with the pipeline during installation, adapting to complex installation scenarios; the right side is an inner threaded interface, with stable connection and reliable sealing.
  2. Soft sealing structure :The valve seat uses EPDM elastic sealing material, meeting the sealing test requirements of "GB/T 13927 Industrial valves Pressure test", ensuring zero leakage of the medium.
  3. Miniature handle operation :Equipped with a black engineering plastic mini handle, conforming to "GB/T 12222 Connection of multi-turn valve actuators", 90° rotation can complete opening and closing, with small operating torque, suitable for installation in small spaces.
  4. Brass valve body material :The valve body is made of H59 brass casting (golden appearance), conforming to "GB/T 12225 General valves Copper alloy castings technical conditions", with excellent corrosion resistance, suitable for water, neutral liquids and other media.
