Flanged fully welded ball valve
Main parts material
Body-carbon steel
Ball-stainless steel
Seal:EPDM or PTFE
1. This valve is an integral welded ball valve made of carbon steel seamless steel pipe.
2. The valve stem is made of AISI303 stainless steel, and the valve body is made of AISI304 stainless steel. They are made by precision machining and grinding, and have excellent sealing performance and corrosion resistance.
3. The seal adopts carbon-reinforced PTFE slope elastic sealing ring with negative pressure on the spherical surface, so that the seal can achieve zero leakage and long service life.
4. The valve connection method: welding, thread, flange, etc. are available for users to choose.Transmission mode: It adopts handle, turbine, pneumatic, electric and other transmission structures, and the switch is flexible and light.
5. This valve has compact structure, light weight, easy heat preservation and easy installation.This valve is generally installed horizontally.

Q:What are the advantages of welded ball valves
A:
1. The valve body structure is integrally welded and there will be no external leakage
.2. The valve seat is composed of a PTFE sealing ring and a spring. It has strong adaptability to pressure and temperature changes and will not cause any leakage within the range of use.
3. The anti-leakage structure of the valve stem. There is a PTFE self-sealing gasket and an O-ring at the bottom of the valve stem. There are 2 O-rings and two PTFE gaskets on the top to ensure no leakage.
4. The valve body material is the same as the pipe material, so there will be no uneven stress and no extrusion and deformation due to earthquakes and vehicles passing over the ground.
5. The valve body is light and easy to keep warm.
6. Directly buried ball valves can be buried directly underground. There is no need to build tall valve wells. Instead, only small shallow wells are needed on the ground, which greatly saves construction costs and engineering time.
7. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
8. The processing accuracy of the sphere is very precise and easy to operate without any adverse interference.
9. There are two connection methods: welding and flange.
10. Operation mode: handle, gear (vertical/horizontal)
11. Under normal operation and use of the valve, the warranty period is 20 years.
