Material Details: The valve body is integrally cast by lost foam casting process. The surface is sprayed with blue epoxy powder coating with a thickness of ≥250μm, and the anti-corrosion grade reaches ISO 12944 C5 level. The sealing seat is made of food-grade rubber, complying with drinking water hygiene standards.
- Core Performance: It adopts a non-rising stem parallel double gate plate structure. The gate plate can automatically compensate for wear, ensuring long-term stable sealing performance. Socket weld connection requires no welding for installation, only rubber ring sealing, which improves construction efficiency by 30%.
- Model Specifications: Nominal diameter DN80 to DN200, pressure rating PN16. It is suitable for ductile iron pipes complying with GB/T 13295 standard. It can provide drinking water certifications such as NSF and WRAS.
- Application Scenarios: Waterworks, secondary water supply, rural drinking water safety projects, serving as the core control valve for civil water supply systems.
