Pneumatic short jacket ball valve is an advanced solution for conveying high viscosity media such as heavy oil and glue that are prone to solidification at room temperature. The valve adopts a jacket structure design, providing insulation or cooling function to maintain the optimal temperature of the medium during transportation and ensure efficient operation.
The valve body is made of carbon steel and equipped with a welded jacket, which improves its pressure resistance and structural integrity. Flange connections facilitate installation into existing piping systems, ensuring flexibility and reliability when handling viscous fluids. The valve is also equipped with flexible graphite packing and high-quality stainless steel balls, ensuring tight closure and long-lasting sealing performance even in harsh environments.
This valve is typically used for high-pressure applications, with a temperature tolerance range of -20 º C to 250 º C. It is suitable for handling liquid and semi-solid media in large pipeline systems.
●Jacketed Design:Provides heat preservation and cold insulation, ensuring stable media temperature during transport.
●Flanged or Wafer Connection:Allows for flexible and secure installation into existing pipeline systems.
●Heat-Resistant Materials: Jacket made from stainless steel and carbon steel body for improved pressure resistance and durability.
