Do you know the cause of the seal failure of the stainless steel ball valve? There are many reasons for seal failure, and the following two are the most common.
1. Natural failure caused by long-term use
The seal of the stainless steel ball valve is always in the medium, and the seal will fail after the sealing element reaches the service life.
Second, the seal damage caused by the large fluctuation of the pump inlet pressure
The pump inlet pressure of the stainless steel ball valve fluctuates greatly, mainly when the pressure is too small, the pressure in the pump chamber suddenly decreases, and the liquid in the sealing chamber flows back into the pump chamber, resulting in dry grinding of the sealing surface, which generates huge heat in a short time and cannot be taken away, so Will burn the sealing surface.
However, the inlet pressure of the stainless steel ball valve pump is too large, and as the pressure increases until it exceeds the value that the seal can bear, the stainless steel ball valve seal will fail.
