Features:
 

  1. Outer leakage won't occur for welded ball valve.
Valve seat consists of teflon sealing ring strengthened by carbon fiber and belleville spring, so it can adjust well to change on pressure and temperature without any leakage risk within marked pressure and temperature range.
  1. The whole process of sphere is tracked and detected with advanced computer and detector, so the process precision is very high, operation is very simple and easy, no bad interference.
  2. Body material is same as material of pipe, when vehicles pass through the ground or even earthquake happens, the stress is evenly distributed without any deformation risk.
  3. Sealing ring is made of PTFE containing 20% carbon, ensure no leakage will happen.
  4. Buried ground fully welded ball valve can be installed in small and shallow well being set on ground rather than large valve well, so the construction cost and project time can be saved a lot.
  5. The length of valve body and height of stem can be designed in accordance with the requirement of project.
  6. The service life can be more than 15 years when used at normal operational and using conditions.

Welding Products

1. Welding Machines - A welding machine is an essential tool for any welding job. It is used to create a welding arc that melts the metal being joined, allowing it to fuse together.

2. Welding Electrodes - Welding electrodes are metal rods that are used to conduct electricity and create an arc. They are coated with a flux that helps to protect the weld from contamination and oxidation.

3. Welding Wire - Welding wire is used in the MIG welding process to feed the welding arc with a continuous supply of wire. It is available in different thicknesses and materials, such as stainless steel, aluminum, and mild steel.

4. Welding Helmets - Welding helmets are designed to protect the welder's eyes and face from the intense light and heat produced during welding. They come in different styles and designs, including auto-darkening helmets that automatically adjust to the brightness of the welding arc.

5. Welding Gloves - Welding gloves are used to protect the welder's hands from heat, sparks, and other hazards associated with welding. They are made from materials such as leather and Kevlar and come in different sizes and styles.

6. Welding Safety Glasses - Welding safety glasses are designed to protect the welder's eyes from the intense light and UV radiation produced during welding. They are available in different shades and styles.

7. Welding Filler Metals - Welding filler metals are used to add material to the weld joint to create a strong, durable bond. They come in different materials, such as stainless steel, aluminum, and bronze.

8. Welding Clamps - Welding clamps are used to hold the metal being welded in place during the welding process. They come in different sizes and styles, including C-clamps, locking pliers, and magnetic clamps.

9. Welding Flux - Welding flux is used to protect the weld from contamination and oxidation during the welding process. It is available in different types, including powder, paste, and liquid.

10. Welding Gas - Welding gas is used in the TIG and MIG welding processes to shield the welding arc from contamination and oxidation. It is available in different types, including argon, helium, and carbon dioxide.
