The metal ring pad is made of metal material by forging and heat treatment and machining , have radial since the tight sealing effect, is a kind of special metal octagonal ring gasket, its action principle is cushion for leaning on and flange type ladder groove (mainly the lateral) out of contact, and through the pressure sealing function to form. It is mainly used for sealing the middle connection of high temperature and high pressure valves.
Metal bonnet sealing ring performance characteristics
1. High temperature resistant, resistant to high pressure, suitable for high pressure valves;
2. Reliable sealing persistent;
3. To adapt to the working conditions of pressure and temperature fluctuations.
