All welded ball valve is made of what material? All welded ball valve is developed and produced according to API6D, api608, gb122237, iso14313 and other standards. It has the advantages of compact structure, elegant appearance and reliable quality. PTFE, rptfe and nylon are used as sealing valve seat respectively. The valve body is made of WCB, WCC, LCB and wc6. It can be installed in class150lb ~ class250lb The range of nominal diameter is 1 / 2 "~ 60"; according to different materials, the applicable temperature can be in the range of - 196 ℃ - 635 ℃.

All fixed ball valve seat support ring is equipped with spring to keep good tightness between valve ball and valve seat seal, and timely compensate the wear between valve ball and valve seat sealing ring, so that the sealing performance of valve ball and valve seat can be optimized and zero leakage can be achieved.

The five technical characteristics of all welded ball valve are introduced. The welded ball valve is widely used in various fields. Its superior quality and high performance stability are beyond the common cast steel ball valve. The service life of the full welded ball valve is far longer than that of the cast steel ball valve. The full welded ball valve is widely used in city gas, city heating, petrochemical, shipbuilding, steel, pressure regulating station, power plant, etc On all kinds of pipeline equipment.

 All welded ball valve

Its technical features are as follows:

1. The valve body structure is welded as a whole without external leakage.

2. The valve seat is composed of PTFE sealing ring and spring. It has strong adaptability to the change of pressure and temperature, and there will be no leakage in the service range.

3. The anti leakage structure of the valve rod, there is a PTFE self sealing gasket and an O-ring at the bottom of the valve rod, and there are two O-rings and two PTFE gaskets on the top to ensure no leakage.

4. The material of valve body is the same as that of pipeline, which will not cause uneven stress and deformation due to earthquake and vehicle passing through the ground.

5. The valve body is light and easy to keep warm.
