INTRODUCTION
A gas welded ball valve is a valve used to control the flow of gas and is characterized by a fixed connection between the ball and the valve body through a welding process, resulting in a tight seal and fluid control. This type of ball valve is suitable for use in a variety of gas piping systems, including domestic, commercial and industrial applications.

  • Tight Welded Connection: The ball and valve body are joined together through a welding process, eliminating removable connection points and ensuring a reliable seal.
  • Safety: Due to the tight welded connection, the gas welded ball valve effectively prevents gas leakage and ensures the safety of the gas system.
  • Fluid Control: By rotating the ball, the flow of gas can be precisely adjusted to meet different needs.
  • Durability: Gas welded ball valves are often made of corrosion-resistant materials that can withstand the chemicals in the gas, increasing the durability of the valve.
  • Easy Operation: Gas welded ball valves are usually equipped with a manual lever, which makes it easy for users to open and close the valve easily.
  • Scope of application: Suitable for a variety of gas systems such as home gas supply, commercial buildings, industrial facilities and so on.

Gas welded ball valve is a kind of valve with tight welded connection, safety and reliability, fluid control ability, used to control the flow of gas, widely used in various gas pipeline systems.

Features and benefits

  1. Valves are designed with forged steel trunnion mounted.
  2. Floating seat.
  3. PMSS or metal-metal seat.
  4. Balls are fixed by internal mounting plate.
  5. Fire safe design as per standard API607/API6FA.
  6. Seat structure could be DBB/DIB/DBB-DIB.
  7. Weled by typical narrow-gap multi-layer submerged arc welding.
  8. Welding seams are inspected by 100% UT and hardness test.

Applications
natural gas, city gas, oil field use

Product Overview
Fully Welded Heating Ball Valve is widely used as an on-off control device in urban heating systems, heat and power pipe networks for water and steam supply, petrochemicals, petroleum, natural gas, pharmaceuticals, and other fields. The valve body is made of high-strength carbon steel seamless pipes or steel plates, which are pressed and formed into a fully welded structure. The ball can be either a floating or fixed structure. The sealing structure of the valve seat is designed as a multi-stage sealing structure with a single or double soft-sealing ring, ensuring reliable sealing and long-term stable operation of this series of ball valves.

Structural Features

  1. The valve stem is made of high-performance stainless steel material with good corrosion resistance. The sealing materials are fluororubber (FPM) and carbonized tetrafluoroethylene (PTFE+C), which are characterized by high strength, high temperature and high pressure resistance, and corrosion resistance. The valve body material uses the same high-strength carbon steel as the pipeline, which will not experience uneven stress, nor will it deform due to earthquakes or passing vehicles. The pipeline is resistant to aging and can also be connected with flanges or other methods according to customer needs.
  2. The ball is made of high-performance stainless steel and the entire manufacturing process is tracked and tested by advanced computer detectors, so the machining precision of the ball is very high, making the operation easy and without interference.
  3. The valve stem is designed to be explosion-proof for safe usage.
  4. The entire assembly process of the valve is completed at a constant temperature, ensuring product quality.
  5. Compared with similar products in the same industry, the valve body design is compact and aesthetically pleasing.
  6. With normal operation and usage of the valve, the service life can reach more than 20 years.
