[valve features]
1, fluid resistance is small, ball valve is the smallest of all types of fluid resistance, even if the diameter of the ball valve, its fluid resistance is quite small.
2, thrust bearings reduce the friction torque of the stem, so that the valve stem can be operated stably for a long time.
3, seat sealing performance is good, using PTFE and other elastic material made of sealing ring, structure easy to seal, and Q41F stainless steel soft sealing ball valve sealing ability with the increase of medium pressure and increase.
4, stem seal reliable, because the stem only for rotational motion without lifting movement, stem packing seal is not easy to destroy, and sealing ability as the medium pressure increases.
5, because PTFE and other materials have good self lubrication, and ball friction loss is small, so long service life of the ball valve.
6, downloading the stem and the stem head convex order to prevent the stem spray, such as stem seal damage caused by fire, convex order and the body can be formed between the metal contact, to ensure that the valve stem seals.
7, Antistatic function: a spring is arranged between the ball, the valve stem and the valve body, so that the static electricity generated by the switching process can be exported.

[Adaptive condition]

       The valve is an important executive mechanism of industrial automation control system, remote centralized control can meet the needs of computer program; now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, tank equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, the preferred product is construction of national defense construction, science and technology.
