Q61F hyperbaric welding ball valve forging by downloading all the parts are the stem-type, equipment down sealing structure, the use of mosaic seat, seat O-ring behind the equipment to ensure that the media does not leak, sealing surface 1010, it coefficient of friction is usually Babbit 1 / 3, so it is a natural sliding of the material. However, flexural strength and impact strength and high ductility, and metal par.
