I. Core Structural Features

This product is a external threaded angle fire ball valve ,The structure conforms to national standards such as "GB/T 12238 Flanges and double-clamp connection ball valves" and "GB 5135.11 Automatic sprinkler fire extinguishing systems Part 11: Terminal test water devices", the core structural features are as follows:
  1. Angled flow path design :The inlet and outlet are at a 90° angle, suitable for 90° turning connection scenarios of fire pipelines, with smooth flow path and low hydraulic resistance.
  2. External thread connection :The inlet and outlet use external threaded connections (conforming to "GB/T 7306 55° sealing pipe threads"), easy to install, reliable sealing, suitable for branch connection of fire pipelines.
  3. Handle operating mechanism :Equipped with a red handle, small operating torque, the handle rotates 90° to complete opening and closing, conforming to the human-computer engineering requirements of "GB/T 12222 Multi-turn valve drive device connection".
  4. Soft sealing structure :Uses elastic sealing elements such as EPDM, excellent sealing performance, meets the sealing test requirements of "GB/T 13927 Industrial valves Pressure test", no leakage under fire conditions.
  5. Brass valve body material :The valve body is made of brass (golden appearance) casting, compact structure, high strength, good corrosion resistance, suitable for long-term use in fire pipelines.
