The application of ball valve
1. NaturaI gas industry
2. Petroleum products
3. Power station boiler
4. Petrochemical industry
7. City construction
8. Environment protection
The Advantage of Ball Valve
1,Fluid resistance small
2. Structure simple, small size, light weight.
3. Closely reliable, sealed surface material widely used plastic
4.Easy to operate, the closing rapidly, from open all around, as long as there 90E, facilitate remote control.
5. Maintenance convenience ,Ball valve structure simple.
6..Ball valve whole or in the open all closed, spheroid and the sealed surface with medium ,valve seat separation medium through, will not cause the valves sealed surface erosion.
7. Widely range in application
Why Choose US
We control the material of PTFE(Teflon) and stainless steel wires per customer's request.
Some are from Japan and Taiwan, some are from China local. Only choose high quality material.
We test leakage of each roll before braiding, then we cut 300mm and crimp it to test
burst pressure after brading.
We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection
tools are all imported from Japan.
We use Techmaflex Crimping Machine which is imported from France. This machine has
accurate and stable performance for crimping because it is produced for PTFE hose crimping only.
