1. Wear resistance;Because the valve core of the hard-sealed ball valve is alloy steel spray welding,
The sealing ring is alloy steel surfacing, so hard sealing ball valve will not produce too much wear when switching.(its hardness coefficient is 65-70) :
Ii. Good sealing performance;As a result of hard seal ball valve seal is used by manual grinding, until the valve core and seal ring can be used completely.So his sealing performance is reliable.
Light switch; 3.Because the sealing ring bottom of the hard sealing ball valve USES a spring to make the sealing ring and the valve core tightly embrace together, so the switch is very light when the outside force exceeds the pre-tightening force of the spring.
Long service life: it has been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rocket and other departments, as well as People's Daily life.
Pneumatic ball valve structure is simple and compact, reliable seal, easy maintenance, sealing surface and sphere are often in the closed state, not easy to be eroded by the medium, easy to operate and maintenance, suitable for water, solvent, acid and natural gas and other general working medium, mainly used to cut or connect the medium in the pipeline, can also be used for fluid regulation and control.
Compared with other types of valves, pneumatic ball valve has angular stroke output torque, open quickly, stable and reliable, widely applicable, and some of the following advantages:
1, the thrust bearing reduces the stem friction torque, can make the stem long-term operation smooth and flexible.
2. Anti-static function: spring is set between ball, valve stem and valve body to export the static electricity generated in the switching process.
3, because ptfe and other materials have good self-lubrication, friction loss with the ball is small, so the service life of pneumatic ball valve is long.
4, fluid resistance is small: pneumatic ball valve is the least fluid resistance in all valve categories, even if the pneumatic ball valve with reduced diameter, its fluid resistance is quite small.
5, valve stem seal reliable: as the valve stem only rotation and not do lifting movement, stem packing seal is not easy to damage, and sealing capacity with the increase of media pressure and increase.
6, good valve seat sealing performance: using ptfe and other elastic materials made of the ring, the structure is easy to seal, and the valve sealing ability of pneumatic ball valve increases with the increase of medium pressure.
7, the fluid resistance is small, the full diameter of the ball valve basically no flow resistance.
8. Simple structure, small size and light weight.
9. Tight and reliable.It has two sealing surface, and the sealing surface material of the ball valve is widely used in all kinds of plastics.It is also widely used in vacuum system.
10, easy to operate, fast open and close, from full open to full close as long as the rotation of 90°, easy to remote control.
11, easy maintenance, ball valve structure is simple, the sealing ring is generally active, easy to remove and replace.
12, when fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the sealing surface of the valve.
13, wide range of application, diameter from a few millimeters to a few meters, from high vacuum to high pressure can be applied.
14, because the ball valve in the opening and closing process of wiping, so can be used with suspended solid particles in the medium.
15. High processing accuracy, high cost, high temperature is not suitable for use, such as impurities in the pipe, easy to be blocked by impurities, leading to the valve can not open.
