I. Core Structural Features
- 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.
- 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.
- 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.
- 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.
