The thrust bearing reduces the friction torque of the stem, which can make the stem operate smoothly and flexiblyfor a long time.
Metal body lined valves: such as rubber lined valves, fluorine lined valves, lead lined valves, plastic lined valves, enamel lined valves.
The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length. Simple structure, small volume, light weight.
