High-Temperature Casting Butterfly Valve is a butterfly valve specifically designed for high-temperature environments, primarily used for regulating or cutting off the flow of medium in high-temperature gas pipelines. This valve integrates advanced foreign technology with domestic manufacturing processes and is widely used in industries such as metallurgy, building materials, chemicals, power stations, and glass.

Structural Features

High-temperature casting butterfly valves typically feature a triple eccentric multi-layer metal hard seal structure. The sealing surfaces are made of stainless steel and hard alloy materials, combining the advantages of elastic sealing and metal hard sealing. The valve seat and butterfly plate are designed with a triple eccentric configuration, significantly reducing wear and achieving a "the tighter it closes, the better the seal" effect.

Application Fields

High-temperature casting butterfly valves are suitable for high-temperature environments with medium temperatures of ≤425°C, primarily used in metallurgy, power, petrochemicals, and municipal construction sectors. Due to their excellent sealing properties and high-temperature resistance, these valves perform outstandingly in these fields.

Performance Parameters

The main performance parameters of the high-temperature casting butterfly valve include its operating temperature range, pressure class, and sealing performance. Specific parameters may vary between manufacturers and models, but they typically meet the usage requirements in high-temperature environments.
