Stainless Steel Flange Insulation Ball Valve
Product Description
-Zero friction when open and close, this function solved the seal problem which is caused by the friction of different sealing surface;
-Mounted type structure, reduced the cost by stopping of the device;
-Single valve seat design, avoid the security problems caused by the abnormal boost of the media within the valve body;
-Low torque design, wedge seal structure, Based on the mechnical press from the stem, valve could press the wedge to the valve seat to seal, thereby the sealing performance can't affected by the line pressure difference, the seal performance could be guaranteed in all conditions;
-Self clean structure on the seal surface, when the ball leans away from the valve seat, the fluid in the pipeline passes 360 degrees across the globe and passes evenly, it not only eliminates the erosion of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
