Main purpose of the product
In recent years, the company has found through market research that when installing and maintaining conventional flange semi-ball valves, large valve well is required, with large installation work amount and high cost. It also forms dangerous closed space in the operation area, which is not conducive to safe operation. At the same time, the valve body and the bolted connection part of the valve body and the pipeline will be subject to corrosion, affecting the service life of the valve. In order to solve the above problems, the company developed a new generation of products - welded eccentric semi-ball valve (directly buried).
The connecting part of the welded eccentric semi-ball valve (directly buried) basically has no leakage. It only needs to build a small shallow well on the ground to reduce construction space and greatly save construction cost and engineering time. The extension rod of different length can be selected according to the actual situation. The actuator can be directly installed above the ground or at the height close to the ground, therefore, the operator can operate on the ground rather than underground, which is very safe and convenient. The good technical characteristics of welded eccentric semi-ball valve (directly buried) make the whole pipeline (all welded) as a whole, which enhances the overall stress resistance, resistance to geological disasters (such as geological collapse) of the pipeline (including the valves), and reduces the possibility of medium leakage. The valve reliability is increased, its service life is extended and the installation and maintenance are very convenient.
