Orbit ball valve is characterized by open friction-free, small torque, good sealing performance and is widely used in high temperature and pressure applications like natural gas molecular sieve dehydration plant, hydrogenation plant, natural gas measuring station, large acetylene device. The orbit metal seated ball valve is opened and closed by the track guide groove of the valve stem. Rotate the hand wheel to detach the ball from the sealing surface of the seat in the process of rotation, and then push the ball toward the seat to realize the seal. Orbit ball valve in the pipeline is mainly used for emergency cutting off, distribution and direction change of the flow. According to the form of structure, it can be divided into floating ball valve, trunnion mounted ball valve and elastic ball valve.
