Stainless steel ball valve
尝辞肠补迟颈辞苍：Home > Stainless steel ball valve
High-temperature ball valve for the metal seal structure, the seal in the form of metal-to-metal seal, the exchange of metal seal on the metal seal, stainless steel and graphite composite plate seal on the metal seal. Hard seal butterfly valve driven form in addition to electric there are manual, worm gear transmission, pneumatic and so on. High temperature ball valve disc installed in the pipe diameter direction. In the hard-sealed ball valve body cylindrical channel, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0 ° and 90 °, and when it rotates to 90 °, the valve is fully opened.
