Reasons and treatment methods for Ball Valve not closing tightly

November 07, 2024
During the use of Ball Valve, there are often some troubling problems, such as the Ball Valve not closing tightly or not closing tightly. What should we do?
Special ball valves for industrial use
Generally speaking, if it is not closed tightly, first check whether the Ball Valve is closed in place. If it is closed in place, there is still leakage and cannot be sealed, then check the sealing surface. Some Ball Valve have detachable sealing pairs, so take them out for grinding and test again. Of course, if it is still not closed tightly, it must be returned to the factory for inspection or replacement of the Ball Valve to avoid affecting the normal use of the Ball Valve and causing working accidents.
If the Ball Valve is not closed tightly, you should first find out where the problem is, and then solve it according to the corresponding method. There are several reasons why a Universal Valve may not close tightly:
(1) There are impurities stuck on the sealing surface, debris deposited at the bottom of the Ball Valve or between the valve disc and the valve seat;
(2) The Valve Stem thread is rusted and the Universal Valve cannot rotate;
(3) The sealing surface of the Ball Valve is damaged, causing leakage of the medium;
(4) The valve stem and the valve disc are not connected well, causing the valve disc and the valve seat to be skewed and unable to make close contact.
