One component that is essential to the vacuum system is the vacuum valve. The rubber sealing ring, one of its essential parts, is crucial to guaranteeing the valve's ability to seal.
Elastic O-rings (O-rings)
One of the most popular seals for vacuum valves is the elastic O-ring. With its circular cross-section, it offers superior sealing capabilities at the valve junction. Rubber materials that are often utilized include silicone rubber (VMQ), fluoroelastomer (FKM), and nitrile rubber (NBR). The size specifications of O-ring seals typically meet with international standards, such as ISO 3601 and AS568 (American standard), depending on the demands of the application and size requirements.
Flat gaskets
In the flange connection section of vacuum valves, flat sealing rings are frequently employed. Rubber or rubber and metal composite materials, which have excellent sealing qualities and corrosion resistance, are typically used to make them. The ASME B16.21 (American standard) and EN 1514 (European standard) are two examples of pertinent international standards that are typically followed by the size specifications of flat sealing rings.
V-rings
In the flange connection section of vacuum valves, flat sealing rings are frequently employed. Rubber or rubber and metal composite materials, which have exceptional sealing qualities and corrosion resistance, are typically used to make them. The ASME B16.21 (American standard) and EN 1514 (European standard) are two examples of pertinent international standards that are often followed by the size specifications of flat sealing rings.
Other special types of seals
Other specific sealing ring types, such as rubber diaphragm seals or piston seals, may be needed in some unique vacuum valve applications. Specific design specifications and manufacturer discretion typically dictate the kind and size standards for these seals.
Summarize
Your vacuum valve's sealing and functionality depend on the rubber seal you choose. To guarantee the quality and dependability of the sealing ring, take into account the valve's operating conditions, temperature range, media requirements, and other elements while deciding one. You may also consult the pertinent dimensional standards. Linde Polymer offers sealing rings that satisfy industry standards, guaranteeing vacuum valves operate dependably.
