What's It Like to Vacuum Ball Valves Specification?
Vacuum ball valves are specifically designed for use in vacuum applications where a tight seal is required to maintain the integrity of the vacuum system. These valves are commonly used in industries such as semiconductor manufacturing, aerospace, and research laboratories.
Here are some common specifications for vacuum ball valves:
Size Range: NW 16 – ISO 160 (3/4” – 6”) custom ends available
Temperature Range: -450 c (-500 F) to 246’C (475’F)
Standard Operating temperature: 302 F
Stem Seal: Double VitonR Quad-ring seal standard
Ball seats: TeflonR
Leak rate: Less than 1 X 10-9 std.cc/sec.
Actuation Types: Manual (handle), Pneumatic, gearbox or combination.
Air to open air to close, air to open spring to close
Standard Valve parts material: 304, 316L (low carbon) Stainless Steel
Pneumatic Operating Pressure: 80-120 psi
Connection Type:threaded, flanged, or welded connections
Actuation: Vacuum ball valves can be manually operated or actuated using pneumatic or electric actuators.
When selecting a vacuum ball valve, it is important to consider the specific requirements of the application, including the vacuum level, flow rate, temperature, and compatibility with the process media. Consulting with a valve manufacturer or supplier can help ensure the right valve is selected for the specific vacuum system.
