What is fully welded ball valve:
The fully welded ball valve is a ball valve that is specially designed and differs significantly from traditional ball valves. Its most notable feature is that the valve body is connected to the enclosed ball through full welding instead of the conventional flange connection.


Applicable occasions of fully welded ball valves:
Fully welded ball valves are commonly used in various industries, including oil and gas transmission pipelines, chemical control systems, city heating systems, as well as the food and pharmaceutical industries.


Why choose LYV®️ valves:
We produce ball valve for over 30 years. The workshop covers 13000 square meters and own more than 50 advanced CNC machines. Our engineers & production team will make sure your order delivers with high-quality and fastest time. We also care about valve shipping. The valves will wrap by bubble pouches or paper to ensure the paint will not be damaged. We also fixed valve by plywood stick after we put valve into the box. The plywood case will be painted with necessary marking to make sure the valve will not be damaged during shipping.
