Full Welded Ball Valve Introduction

Full Welded Ball Valve Introduction
Full Welded Ball Valve Application:
 Full welded ball valve can be used for following pipelines:
1. City Fuel Gas supplying: Gas output pipeline, trunk pipeline and separate regional supplying pipeline
2. Central heating system: Large heating equipment output pipeline, trunk pipeline and feeder.
3. Heat Exchanging system: Piping and the opening and closing of each circuit.
4. Steel mills: All kinds of fluid pipes, exhaust pipes, fuel gas and heat supplying pipes, etc.
5. Various Industrial equipment like heating treatment pipeline, industrial gas and heating supplying pipeline, etc.

Full Welded Ball Valve Characteristics:
1. One Piece Fully welded ball valve won't have external leakage problem. Fully welded ball valve seat is made of Carbon Fiber reinforced Teflon seal and Clip Spring, which can be adaptable to the changes in pressure and temperature, and it won't cause any leakage within the applicable pressure and temperature range.
2. Valve Body material is the same as Pipe material, which won't cause uneven stress from medium. It won't cause deformation because of earthquake or vehicle passing through it.
3. Undergrounded fully welded ball valve or embedded fully welded ball valve can be buried underground directly, thus,it's unnecessary to build high and large valve well, small valve well is enough, which greatly reduced construction cost and project time.
4. Ball Valve Length and Stem Length can be adjusted according to exact construction or design requirement.
5. The machining accuracy of Valve Sphere or ball is very precice and can be operated conveniently.
6. Compared to other ball valves with the same specification, Fully welded ball valve is with small body, beautiful shape and long service life.
 

Fully welded ball valve installation:
1. All the Steel fully welded ball valve ends welding should adopt Electro welding or Handwelding.
2. During welding, valve Chamber Overheating problem should be avoid.
3. Welding end distance to valve seat shouldn't be too short, in case the welding heating damaged the sealing ring.
4. Valve should keep open during installation.
