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