Butterfly Valve

MeiDe , China’s No.1 industrial butterfly valve manufacturer since 2001, delivers API 609-certified solutions for 140+ countries. Key advantages:
Extreme Temperature Range: Operates at -40°C~800°C (-40°F~1472°F) with triple-offset metal seats (API 607 fire-safe) or EPDN/PTFE for cryogenic/chemical service.
Zero Leakage: ≤1ppm fugitive emissions (ISO 15848-1) and Class V sealing @ 10bar (ISO 5208).
Compact & Efficient: 60% lighter than gate valves, full-bore design minimizes pressure drop (EN 593 compliant).
Automation Ready: ISO 5211 mounts for pneumatic/electric actuators (ROTORK/ABM compatible), reducing installation time by 40%.
Durability: 100,000+ cycles (AWWA C504) with corrosion-resistant 316L/Hastelloy trim (NACE MR0175).
Certifications: API 609/607, SIL 3, ATEX, CE, GOST, ISO 15848-1.
Applications:
Thermal Power: 800°C steam isolation (API 607).
LNG/Cryogenic: -196°C extended stem valves (BS 6364).
Wastewater: EPDM-lined wafer valves for 30% solids.
Chemical: PTFE-seated lug valves for acids/alkalis.
With 10-day lead times and global compliance, MeiDe ensures reliability across oil/gas, power, and chemical industries.
