High temperature control valves are engineered to operate reliably under extremely high temperatures, utilizing durable metallic materials with very high melting points. These power-operated valves regulate the flow of fluids like gas, oil, water, and steam by adjusting the flow passage size based on control signals. They are particularly suited for industries such as petrochemical, chemical fertilizer, electric power, and metallurgy, ensuring robust performance and accuracy in environments where standard valves might fail due to extreme heat.
