41 Sphere - EPDM Soft Sleeve - 304 Stainless Steel with Edge Plate - 420 Shaft - Electric Head

Detailed introduction:

The electric flanged butterfly valve is a common industrial valve; here's an introduction to it:
Structural Components: Consists of a valve body, butterfly disc, valve stem, sealing ring, electric actuator, and more. The valve body is typically made from materials such as cast iron or cast steel, with flanges at both ends. The butterfly disc is disc-shaped and mounted on the valve stem. The electric actuator provides the driving force, transmitting motion via a connecting bracket and coupling to rotate the valve stem.
How it works: The electric actuator receives a control signal, which activates the motor to rotate. This rotation is then transmitted through a reduction mechanism, turning the valve stem and causing the butterfly disc to move within a range of 0° to 90°, thereby enabling the valve to open or close, or to regulate flow.
Performance features: Simple structure, compact size, lightweight design, convenient operation, rapid opening and closing, excellent fluid control capabilities, and minimal pressure drop.
Sealing types: There are two options—soft sealing and metal sealing. Soft sealing uses materials like rubber, offering excellent sealing performance and suitable for media at ambient temperatures. Metal sealing, on the other hand, withstands high temperatures and pressures but can be more challenging to achieve a completely tight seal.
Technical specifications: The nominal diameter typically ranges from DN50 to DN1200 mm, with a nominal pressure rating of PN1.0 to PN2.5 MPa. The applicable temperature range varies depending on the sealing material, generally falling between -20°C and 400°C.
Application areas: Widely used in industries such as petroleum, chemical engineering, metallurgy, water treatment, and power generation, for controlling the flow of media like air, water, steam, and oil products.
