There are many reasons for valve leakage, the following are three reasons for valve leakage.

First, the valve leakage caused by unqualified sealing surface production. In practical applications, the roughness of valve sealing surface and the application(globe valve application in industry) of sealing material have a profound impact on the quality of valve. Second, improper manual operation of the valve caused by internal leakage. In practical operation, if the operator applies the valve too hard or too fast on the site, some parts of the valve will be damaged, and even the sealing surface of the valve will be damaged, accelerating the consumption of parts and components and causing internal leakage. Third, the connection between the valve ring and seat is not tight enough to cause the problem of valve leakage. Affected by the deformation of valve stem and the error of some parts, the sealing surface of valve cannot be tightly fitted together, so the sealing protection function of valve sealing surface cannot be played, leading to the occurrence of valve internal leakage.

ZJCLV valve through professional design like globe valve design calculation, strict production in accordance with the standard, the last several times in accordance with the requirements of professional testing of the valve. Top quality.
