Main functions and technical parameters of the product
MeiDe Valve produces Tilting Disc Check Valves API 6D-certified design ensures zero water hammer with hydraulic-damped closure (0.3s). Key benefits:
- Anti-Erosion Tilted Disc: 8° angled Stellite 6 overlay (HRC 68) reduces seal wear by 70% in turbulent flows.
- Low-Pressure Activation: 0.1bar cracking pressure for energy-efficient operation (ASME 150-2500#).
- 360° Installation: Omnidirectional mounting with 1.2mm misalignment tolerance (ANSI Class VI ≤2ppm).
- Extreme Durability: 1M+ cycles (-46°C~550°C) with PTFE/NACE MR0175 options for viscous/H₂S media.
- Compact Flow Design: 98% bore utilization minimizes Δ Ideal for oil/gas, chemical, and power pipelines.
