Parri - Model DN10-DN1600 -Manual Ball Valve
Fully welded ball valve is welded after sheet metal is forged and pressed. The weight is about 10-20% lighter than bolted structure ball valve, and valve volume is also small. It also reduces potential external leakage from connection of body and bonnet and improves the reliability of the valve, so it has a long service life, is the best choice for long distance transport pipes. The seat is made of a carbonized Teflon seal ring and a disc spring, so it is adaptable to changes in pressure and temperature, and does not cause any leakage within the pressure and temperature range.
The processing of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high. Since the valve body material is the same as the pipe material, there will be no uneven stress, and it will not be deformed due to earthquakes and vehicles passing through the ground. Fully welded ball valve can also be buried in the ground. It is not necessary to build a large valve well. It is only necessary to set up a small shallow well on the ground, which greatly saves construction costs and engineering time.
