Main functions and technical parameters of the product
MeiDe Valve produces Dual Plate Check Valves API 594-certified design ensures zero leakage (≤2ppm) with spring-assisted dual discs for instant closure (15ms). Key benefits:
- Compact & Lightweight: 50% shorter than swing checks (ASME 150-2500#), ideal for tight spaces.
- Corrosion Resistance: Stellite 6/TC overlay (HRC 65+) withstands -46°C~550°C extremes.
- Water Hammer Control: Hydraulic damping limits impact to ≤2x system pressure.
- Omni-Directional: Horizontal/vertical installation with 0.1-0.3bar cracking pressure.
- Retainerless Body: Zero threaded penetrations meet ISO 15848-1 fugitive emission standards. Perfect for oil/gas, chemical, and power plants.
