Ball Valve Smooth And Reliable, Widely Applicable

1. Wear-resistant; as a result of hard seal ball valve is alloy steel spray welding, three-piece ball valve seal is alloy steel surfacing, so hard seal ball valve in the switch will not produce too much wear. (Its hardness factor is 65-70);
2. Sealing performance; due to the seal of the hard seal ball valve is used artificial grinding, until the spool and seal ring can be used in order to fully use. So his sealing performance is reliable.
3. Switch light; as a result of hard seal ball valve ring at the bottom of the spring so that the seal ring and the spool firmly together, so the force in the external force exceeds the spring preload when the switch is very light.
4. The service life; has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
Pneumatic ball valve compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical surface is often closed, not easily eroded by the media, easy to operate and maintenance, for water, solvents, acids and natural gas and other general working medium, In the cut-off or connected to the pipeline in the medium, can also be used for fluid regulation and control.
Pneumatic ball valve compared with other types of valves, with angular travel torque, open quickly, smooth and reliable, wide range of applications, etc. The following advantages:
1. thrust bearing to reduce the stem friction torque, the stem can be long-term operation smooth and flexible.
2.anti-static function: in the sphere, stem, valve body set between the spring, the switch can produce static electricity derived.
3. due to PTFE and other materials with good self-lubricating, and the ball friction loss is small, so the use of pneumatic ball valve long life.
4. the fluid resistance is small: Pneumatic ball valve is the valve in all the classification of the smallest resistance to a fluid, even the reduced diameter pneumatic ball valve, the fluid resistance is also quite small.
5. the stem seal is reliable: the stem as only imitation and movement without lifting movements, stem packing seal is not easy to damage, and the sealing capacity increases with the pressure of the media increases.
6. the valve seat sealing performance: the use of PTFE and other elastic materials made of seals, the structure is easy to seal, and pneumatic valve valve sealing capacity increases with the media pressure increases.
