Main functions and technical parameters of the product
MeiDe Valve produces stainless steel check valve AISI 316/304 valves offer corrosion-resistant reliability for harsh environments. Key benefits:
- Zero-Leakage Sealing: Hardened Stellite 6/PTFE seats achieve ANSI Class VI (≤2ppm) in chemical/seawater service.
- Quick Closure: Spring-assisted disc shuts in 0.3s, preventing water hammer (API 6D/ASME B16.34).
- Full-Bore Design: 100% flow efficiency with ASME 150-2500# pressure rating (-196°C~600°C).
- Omni-Directional: Horizontal/vertical/angled installation with NACE MR0175 trim for Hâ‚‚S environments.
- Maintenance-Free: 10+ year lifespan in pharma, desalination, and acidic media pipelines.
