Shrink diameter welding flanges ball valve

The role of reduced flange welding ball valve is as follows:

Body structure integral welding, there will be no external leakage phenomenon.

The valve seat is composed of PTFE sealing ring and spring to adapt to changes in pressure and temperature, and will not produce any leakage within the range of use.

The anti-leakage structure of the valve stem, the bottom of the valve stem has a PTFE self-sealing gasket and an O-ring, which is composed of 2 O-rings and two PTFE gaskets to ensure no leakage.

The material of the valve body is the same as that of the pipeline, and there will be no uneven stress, and it will not be squeezed and deformed due to earthquakes and the vehicle passing through the ground.

Body is light and easily insulated.

Directly buried ball valve can be directly buried in the ground, no need to build a tall valve well, just set a small shallow well on the ground, greatly saving construction costs and engineering time2.

The length and stem height of the valve body can be adjusted according to the construction and design requirements of the pipeline.

The processing precision of the ball is very precise and the operation is light and without bad interference.

In the case of normal operation of the valve, the warranty period is 20 years.

Full-welded ball valve with reduced flange is a good energy saving and environmental protection product, which features that the internal leakage can reach "zero leakage" when the valve is closed, which can reduce the loss caused by energy loss to the lowest point

The application scenario of reduced flange welding ball valve mainly includes the following aspects:

City gas: gas output pipeline, main line and feeder supply pipeline, etc.

Central heating: large heating equipment output pipeline, main line, branch line.

Heat switch: pipe and circuit opening and closing.

Steel plant: various fluid pipelines, exhaust gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines.

Industrial equipment: all kinds of heat treatment pipes, all kinds of industrial gas and heat pipes.

Packing of Standard Packing:

 Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 2022 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
