special use valve bellows

1.Valve bellows got ISO 2.Materail:304L,AM350,or 316L 3.Thickness:0.08mm-0.2mm 4.Vacuum Leak Rate:1x10^-10Pa.L/S

Valve  bellows are widely used in aerospace, vacuum industry, semiconductor industry, solar energy photovoltaic industry, medical equipments and synchronized radiation accelerator industry and so on.

Products Test:

Our factory is equipped with advanced numerical control lathes, numerical control milling machines, and our factory introduce high-precision automatic welding machines, laser welding machines and plasma welding machines from Korea, and also imported Korean stamping equipments. For better quality test of the welded bellows, it also equipped high precision vacuum life test equipment from Taiwan, Varian VS leak detectors from America, and horizontal rigidity testers from Korea.

Products Design:

Molds and welded bellows sizes can be designed and developed according to customers’ requirements.
