Main functions and technical parameters of the product

MeiDe Valve produces wafer check valve API 594-certified dual-plate design ensures zero fugitive emissions with a retainerless structure (no threaded body penetrations). Key benefits:

  • Fire-Safe Performance: Metal-to-metal sealing post-1000°F exposure (API 607 compliant).
  • Ultra-Compact: 85% lighter vs swing checks, fits all flange types (ASME 150-2500LB).
  • Low Cracking Pressure: ≤5psi ensures smooth flow with 30% lower ΔP.
  • Omni-Directional: Horizontal/vertical installation with spring-loaded discs.
  • ISO 15848-1 Seals: ≤50ppm emissions, ideal for oil/gas/chemical pipelines. Optional NACE MR0175 trim for sour service.
