Stainless steel pneumatic three-piece ball valve


Here are some of the main features and requirements of pneumatic three-piece ball valves:

  • Valve type: Electric/pneumatic ball valve is a kind of equipment used to control the fluid medium, and its main role is to control the home fluid in the off. In industrial production,electric ball valves are usually used to control the flow and pressure of fluid media such as hydraulic oil to ensure the safety and stability of the production process, inaddition, electric/pneumatic ball valves can also be used in fire protection systems, heating systems, air conditioning systems, water supply and drainage systems and other fields

  • Size range: This standard specifies the size range of these valves, typically 15 inches to 100 inches in diameter. The exact size range may vary depending on the manufacturer andproject requirements.

  • Pressure Ratings: Pneumatic three-piece ball valves are typically designed for different pressure levels to accommodate a range of system pressures. The common pressure level isnormal pressure, and the working temperature is normal temperature


  • Materials: This standard defines the materials used in various components of valves, including valve bodies, gates, stems, seats and other internal components. Usually, the body is made of stainless steel, while the gate is usually made of stainless steel laser cutting.

  • Coating: Pneumatic three-piece ball valves have an external coating to prevent corrosion, such as fused epoxy resin (FBE) or other suitable coatings.


  • Medium: water, oil, gas

  • Structural form: three-piece type

  • Temperature: room temperature 0-260°C                      

  • Drive mode: pneumatic Control mode: switch type
