WANVALVE WE20-F-S Electric Flanged Butterfly Valve

The WANVALVE WE20-F-S electric flanged model is engineered for superior automation and long-term durability. As a flow control valve, it provides a secure and leak-free connection that performs flawlessly under high pressure and high temperatures. Designed with an electric actuated system, this flow control valve allows precise quarter-turn operation for accurate valve positioning, ensuring stable control of flow in industrial processes.

This compact unit features a space-saving design and polished surface and polished surface, making it easy to clean and maintain. It is particularly suitable for industries that require hygiene, efficiency, and durability — including water treatment, petrochemical, and food processing plants.

Material and Construction

Constructed from corrosion-resistant steel, this valve offers outstanding mechanical strength, this valve offers outstanding mechanical properties and resistance to corrosion. The chromium content in stainless steel forms a protective chromium oxide layer, giving the valve superior resistance to oxidation and harsh environments.

Different grades of stainless steel—such as austenitic, ferritic, and martensitic stainless steels—can be applied depending on system needs. For more demanding conditions, duplex alloy steel is available, offering a balanced combination of strength and corrosion resistance that outperforms many conventional alloys.

Performance and Reliability

This electric flanged butterfly valve ensures smooth operation and high repeatability. It enables efficient control of flow through a quarter-turn mechanism that reduces wear while maintaining precise alignment. Its compact design allows easy integration into automated control systems, while its strong sealing performance with PTFE/EPDM seats minimizes leakage even under fluctuating pressures.
