Swiss VAT Large High Pressure Swing Isolation Valve 16.8 Series
16.8 Large high vacuum swing isolation valves can provide reliable isolation performance even under harsh process conditions. It is an ideal choice for isolation requirements in high traffic applications, such as large coating or display production systems. Therefore, it offers specifications of DN400 and 500mm. The 16.8 valve offers optional 3-position pneumatic or standard pneumatic, both of which are double acting.
Due to its unique split design, it allows for maintenance without disassembling pipeline connections or process room connections. Its slim design allows for the direct installation of 16.8-inch isolation valves in the process chamber, reducing the volume typically required in the process chamber valve pump connection.
The 16.8 series is easily integrated into various vacuum processes, thanks to its robust design and various design options.
The 16.8 series has been installed in hundreds of batch and online production systems under different process conditions worldwide, demonstrating its outstanding performance in all aspects.
16.8 Large high vacuum swing isolation valves are made of aluminum and have ISO-F and JIS standard flange joints. Can integrate customer specific flanges. Other options include ports for rough machining (bypass), ventilation, or measurement. Due to the frequent use of isolation valves with a size of 16.8 to isolate turbo pumps, splash screens can also be provided.
