Product Overview
Description
Application:
Fixed ball valves are suitable for long-distance pipelines and general industrial pipelines, and their strength, resistance to harsh environments, etc. have been considered in the design, making them suitable for corrosive and non corrosive media.. Spring pre valve seat assembly with self tightening characteristics, achieving upstream sealing. Each valve has two seats that can be sealed in each direction, so there is no flow restriction during installation and it is bidirectional.
