Main functions and technical parameters of the product
MeiDe Valve produces Forged Steel check valve ensures zero backflow with rapid closure (<0.3s) in high-pressure systems. Key benefits:
- High-Temp/High-Pressure: Operates at -46°C~538°C (-50°F~1000°F) up to Class 4500.
- Robust Construction: ASTM A105/A182 F316L bodies resist corrosion/erosion (NACE MR0175).
- Dual Designs: Swing (EPDM seat) for water / Lift (metal-sealed) for steam/oil.
- Anti-Slam: Spring-assisted lift disc prevents water hammer (API 594 tested).
- Longevity: 1M+ cycles (ISO 5208). Ideal for refineries, power plants, and chemical pipelines.
