Pneumatic short ball valves are an innovative solution to deliver high-viscosity media such as heavy oil and glue that can easily solidify at room temperature. The valve is designed with a sleeve structure to provide insulation or cooling function to ensure the optimal temperature of the medium during transportation, thus ensuring efficient operation.
The body is made of carbon steel and coated with welded coating to improve its pressure resistance and structural integrity. The flange connection method is easy to install into existing piping systems, ensuring flexibility and reliability in handling viscous fluids. In addition, the valve is equipped with flexible graphite fillers and high-quality stainless steel balls to ensure long-term sealing in harsh environments.
The valve is generally suitable for high pressure applications with a temperature range of-20℃ to 250℃, and especially for handling liquid and semi-solid media in large piping systems.
●Jacketed Design:Provide insulation and cooling to ensure stable temperature of the medium during transportation.
●Flanged or Wafer Connection:Allow flexible and secure installation into existing pipeline systems.
●Heat-Resistant Materials:The sheath is made of stainless steel and carbon steel to improve pressure resistance and durability.
