Metal seated ball valve Our metal seated ball valve is suitable for harsh work conditions, can be used for a wide temperature range, such as the high temperature, corrosive media and so on. 1.The tungsten-chromium alloy solid stainless steel seat firmed by the spring. This kind of design can be applied to a wide range of operating conditions, it not only improves the seal performance, but also has the excellent features of long service life and maintenace-free. 3.The stable torque is easy to use, and cheaper in cost. 4.High-quality sealing performance, depends on a high leave of processing technology, through this way the ball can have a close contact with seat. 5.Even in a low terperature, the spring installed in the seat can ensure the ball have a close contact with the seat, so in a wide temperature range, under high-pressure difference and high frequency, the torque can still be open and closed stablely. 6.Composed of different materials, the valve can be used for different temperature up to 500 and above. 7.After the surface-harding treatment, the ball valve seat can be more widely used on paper pulp as well as other corrosive occasions, and have a long lifetime. What't more, the fixed ball with an unique design is suitable for the media containing dust. 8.Metal to metal sealed ball valve with its body seat, ball, other metal parts, and so forth, closely contact with each other, having naturally formed a static electricity passage.
