Main functions and technical parameters of the product
MeiDe Valve produces Non Slam Check Valves API 6D-certified design eliminates water hammer with guided hydraulic closure (0.5s shutdown). Key benefits:
- Venturi Flow Path: 30% lower ΔP and 40% turbulence reduction for ANSI 150-2500# systems.
- Zero Impact Closure: Floating disc auto-aligns to 0.5mm misalignment, ensuring ≤2ppm leakage (ANSI Class VI).
- Erosion Resistance: 5mm tungsten carbide-lined throat withstands 60% solid slurries (-46°C~425°C).
- Omni-Directional: 360° installation flexibility (ASME B16.34) with 1M+ cycle durability (API 598).
- NACE MR0175 Option: Inconel 625 trim for Hâ‚‚S environments. Ideal for oil/gas, refining, and power pipelines.
