I. Structural Features and Applications
Structural Features
- Groove Connection Uses national standard grooved connection (compliant with GB 5135.11), quick installation via clamps, no welding required, suitable for conventional pipeline construction, convenient disassembly and maintenance, suitable for small and medium-diameter pipeline systems.
- Visible Stem Design The stem rises and falls synchronously with the gate plate, the valve opening is clearly visible, facilitating on-site observation of the opening and closing status, simple operation, suitable for manual operation under normal working conditions.
- Hard Seal Structure The gate plate and valve seat use stainless steel hard seal matching (meets the basic requirements of GB/T 12232), the sealing surface is regularly machined, suitable for cutting off media under general pressure and temperature conditions.
- Standard Materials The valve body is made of ductile iron, the stem is made of stainless steel, and the surface is treated with basic anti-corrosion, meeting the needs of ordinary industrial and civil pipelines.
