Ball valve advantages
Apr 23, 2018

Advantages: 1 has the lowest flow resistance (actually 0); 2 because it does not get stuck in the work (in the absence of lubricants), it can be reliably applied to corrosive media and low-boiling liquids; 3 in the larger In the pressure and temperature range, it can be completely sealed; 4 can achieve fast opening and closing, some structures open and close time is only 0.05 ~ 0.1s, in order to ensure that can be used in the test bench automation system. When opening and closing the valve quickly, there is no impact on the operation. 5Spherical closing parts can be automatically positioned at the boundary position; 6The working medium is sealed reliably on both sides; 7 When fully open and fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium, so the medium that passes the valve at high speed will not Cause the sealing surface erosion; 8 compact, light weight, it can be considered that it is the most reasonable valve structure for low temperature medium system; 9 valve body symmetry, especially the welded valve body structure, can well withstand the stress from the pipe ;10 The closure can withstand the high pressure difference when it is closed. (11) The ball valve of the fully welded valve body can be directly buried in the ground so that the internal parts of the valve will not be eroded, and the maximum service life can reach 30 years. It is the most ideal valve for petroleum and natural gas pipelines.
