Product overview:
Hard seal ball valve is a kind of rotary valve with 90° Angle, good sealing performance, large flow coefficient, small flow resistance coefficient, simple structure, long service life and easy maintenance. Products are widely used in chemical, petroleum, textile, power, food pharmaceutical, refrigeration, papermaking industry system control.
Product introduction:
Mainly used to cut off or put through the medium in the pipeline, can also be used for fluid regulation and control, compared with other valves, with the following advantages:
1, fluid resistance, Q41 floating ball valve is all the valve class of fluid resistance is the least, even if the reduced diameter ball valve, its fluid resistance is also quite small.
2. The thrust bearing can reduce the friction torque of valve stem, which can make the valve stem balanced and flexible in long-term operation.
3, the seat sealing performance is good, the use of ptfe and other materials made of sealing ring, the structure is easy to seal, and the ball valve sealing capacity with the addition of medium pressure and increase.
4, the valve stem seal is reliable, because the valve stem only for rotating movement and do not do lifting movement, the packing seal of the valve stem is not easy to destroy, and the sealing capacity with the pressure of the medium increased.
5, because the inner parts of ptfe and other materials have good self-lubrication, friction loss with the ball is small, so the service life is long.
6. The lower valve stem and the protruding step of the stem head prevent the valve stem from ejecting. In case of damage of the valve stem seal caused by fire, metal contact can be formed between the protruding step and the valve body to ensure the valve stem seal.
Scope of use: the product can be used in metallurgy, chemical industry and other industries.
Products conform to the standards: GB/T 21385, GB/T 9113.
