In the middle of the valve cover junction valve pressure, has good sealing performance under high temperature and high pressure conditions. There are two kinds of self sealing materials: one is the low carbon steel, the other is a flexible graphite wire clip 316 (net). The sealing surface surfacing cobalt base hard alloy. The processed pure metal layer is larger than 3 mm, with wear-resistant, high temperature resistance and corrosion resistance, abrasion resistance, long service life. The implementatio...
