WANVALVE WE20-LUG-S Electric Stainless Steel Lugged Butterfly Valve
The WANVALVE WE20-LUG-S Electric Stainless Steel Lugged Butterfly Valve combines superior automation, excellent mechanical properties, and secure installation flexibility. Designed for modern fluid control systems, this valve integrates a powerful electric actuated mechanism with a lug-style body, ensuring dependable performance in high-pressure and high-temperature environments. It provides precise quarter-turn operation and excellent sealing for both on/off and throttling control applications, all within a compact design that saves installation space.
Durable Stainless Steel Construction
Built with a high-grade stainless steel body, this actuated butterfly valve provides excellent corrosion resistance and durability. A thin chromium oxide layer naturally forms on the surface, protecting it from oxidation and ensuring a smooth surface finish. Depending on application needs, it can be produced in various grades of stainless steel, including austenitic, ferritic, or martensitic types.
For enhanced strength and longevity, duplex stainless steel is also available as a customized option, providing superior balance between toughness and corrosion resistance. Optional WCB materials are offered for cost-effective installations, while chromium content ensures stable performance in aggressive or sanitary environments. The PTFE or EPDM sealing materials deliver a tight shutoff and are easy to clean, making this valve ideal for food and beverage, water treatment, and chemical industries.
Lugged Connection Design
The lug butterfly configuration allows the valve to be easily installed between flanges using bolts, providing flexibility for systems that may require isolation on either side of the pipeline. The lugged butterfly valve design supports both dead-end and bidirectional service, ensuring reliable sealing performance. Its ANSI, JIS, DIN, and GB standard compatibility makes it suitable for global industrial systems, ensuring secure mounting and maintenance convenience without system downtime. This lug style body is especially valued in modular systems where frequent assembly and disassembly are required.
Electric Actuation and Control
Equipped with a precision electric actuator, this butterfly valve supports automated operation for enhanced control accuracy and efficiency. Similar to other models in the WANVALVE Electric Butterfly Valve Series, it delivers consistent torque output with low noise and supports both remote and manual override in case of power interruption. Integration with industrial communication protocols allows seamless connection with control systems, making it ideal for automated process lines. According to Control Engineering, modern electric actuation enhances process efficiency and reliability across multiple industries.
Smart Control Integration
The electric actuator of the WE20-LUG-S supports advanced automation functions including position feedback, signal adjustment, and remote control. It can be easily integrated into existing control systems such as PLC, DCS, or SCADA platforms. Optional signal types like 4–20mA, 0–10V, or Modbus RTU allow precise monitoring of valve position and operation status. This flexibility makes the valve suitable for complex automated pipelines and smart industrial environments, aligning with the evolving standards highlighted by Belimo and Valves Actuator.
