Main functions and technical parameters of the product
MeiDe Valve produces Axial flow check valve ASME 2500-certified design eliminates water hammer with spring-assisted closure (0.2s). Key benefits:
- Ultra-High Flow: Cv 450+ at DN500 (50% higher ΔP efficiency vs swing checks).
- Zero Noise: <65dB(A) operation via streamlined disc guidance (ASME B16.34).
- Corrosion Resistance: Duplex 2205/NACE MR0175 trim for Hâ‚‚S/sour gas (API 6D).
- Full Range Sizing: NPS 2″-60″ (DN50-DN1500) with RF/BW/RTJ connections.
- Rugged Construction: -46°C~550°C operation, 10+ year maintenance-free lifespan. Ideal for LNG, refining, and high-flow pipelines.
