WANVALVE WE20-P Electric Actuated Plastic Butterfly Valve

The WANVALVE WE20-P Electric Actuated Plastic Butterfly Valve is a high-quality electrical valve engineered for precise flow control in industrial and water treatment systems. Designed with a PVC/CPVC body and an electric actuator, it combines durability, corrosion resistance, and a compact design that fits easily into wafer-style installations. With a working pressure of up to 150 psi, this valve delivers consistent performance and tight sealing for both clean and corrosive media. It is ideal for use in chemical plants, marine systems, and other applications that require reliability and efficiency without the weight of stainless steel valves.

Durable and Corrosion-Resistant Construction

Made from UPVC or CPVC materials, the WE20-P provides outstanding corrosion resistance and mechanical strength. The valve’s internal components are engineered for tight sealing, minimizing leaks even under fluctuating pressure and temperature. The EPDM sealing ensures long service life and chemical stability, making it a suitable replacement for stainless steel butterfly valves in environments where metal corrosion is a concern.

Electric Actuation and Manual Override

This electric actuated butterfly valve ensures smooth quarter-turn movement and precise valve position control. The actuator can be configured with various control signals (4–20mA or 0–10V) to integrate seamlessly with automated systems. In the event of power loss, a manual override and lever handle (hand lever) provide reliable backup operation. This flexibility enhances operational safety and ensures continuous control in both automatic and manual modes.
