Characteristics of ball valve
Oct 19, 2016

One, wear-resistant due to hard seal ball valve spool is alloy spray-welding,

Seals are alloy steel welding, hard seal ball valves can switch without causing too much wear. (Hardness coefficient of 65-70):

Two good sealing performance due to using artificial grinding hard seal ball valve seal is, until the valve and sealing ring fully before use. So he is the sealing property is reliable.

Three switch light; because hard seal ball valve sealing ring at the bottom using springs that keep the seal and poppet tightly together, so the external power switch when the preload of the spring is very light.

IV long life: it has been widely used in petroleum, chemical, power generation, paper, nuclear energy, aviation, rocket and other departments, as well as in people's daily lives.

Pneumatic ball valve structure is compact, it is reliable to seal, simple structure, easy maintenance, sealing surface and a spherical often closed, not easy to medium wash, easy operation and maintenance, suitable for water and gas, solvents, acids and other working media, mainly used to cut off or put through the medium in the pipeline, can also be used for the adjustment and control of fluid.

Compared with other type of pneumatic ball valve, with angular stroke output torque, open fast, stable and reliable, versatile, and a number of advantages.

Reducing valve 

1, thrust bearing friction moment can stem the long-term stable and flexible operation.

2, anti-static feature: in the spring among spheroid, valve stem, valve, can export the static electricity generated by the process of switching.

3, have good self-lubricating materials such as PTFE, sphere's friction loss is small, so the long service life of ball valve.

4, small resistance for fluid: pneumatic ball valve is the valve all fluids in the classification of least resistance, even reduced ball valve, the fluid resistance is also quite small.

5, the valve stem seals and reliable: since the stem only seems to turn games without lifting movement, valve stem packing seals easy destruction and sealing ability increases with increased pressure of the medium.

6, the valve sealing performance: PTFE sealing ring made of elastic material, easy to seal, and pneumatic ball valve with medium pressure increases.
