Ball valve in the pipeline is mainly used to do cut off, distribution and change the direction of flow of media, it only needs to rotate 90 degrees of operation and a very small turning torque can be closed tightly. Ball valves are most suitable for switching, cut-off valve use.
1.wear-resistant:because the spool of hard seal ball valve is alloy steel spray welding, the Seal ring is alloy steel surfacing, so hard seal ball valve in the switch will not produce too much wear. (Its hardness coefficient of 65-70)
2.good sealing performance: because the seal of the hard seal ball valve is manually ground until the spool and the seal ring completely match before use. So his sealing performance is reliable.
3.the switch is light: due to the hard seal ball valve sealing ring at the bottom of the spring so that the sealing ring and the spool held tightly together, so in the outside world force exceeds the spring preload switch is very light.
4.long 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 life.
1. Are you a manufacturer or a trading company?
We are a professional manufacturer with over 20 years' experience for designing and producing casting parts and machining parts.
2. How can I get some samples?
If you need, we are glad to offer you samples for free, but the new clients are expected to pay the mould cost and courier cost.
3. Can you make casting according to our drawing?
Yes, we can make casting according to your drawing, 2D drawing, or 3D cad model, both available. If the 3D cad model can be supplied, the development of the tooling can be more efficient. But if without 3D, based on 2D drawing we can still make the samples properly approved.
4. Can you make casting based on our samples?
Yes, we can make measurement based on your samples to make drawings for tooling making.
5. What's your quality control device in house?
We have spectrometer in house to monitor the chemical property, tensile test machine to control the mechanical property and UT Sonic as NDT checking method to control the casting detect under the surface of cast.
