LYV® is a professional Forged Floating Ball Valve manufacturers and suppliers in China. If you interested in Forged Floating Ball Valve products, please contact with us. We follow the quality of rest assured that the price of conscience, dedicated service. The forged floating ball valves are a floating ball valves that have a body made of forged steel material, which have a broad working temperature range. The end connectors with flange are a typical kind of accessory, in particular they are perfect for low-pressure applications.

These valves are designed to resist wear and provide long-term reliability. They can be used in a variety of applications, including water systems, sewage systems, oil and gas pipelines, and manufacturing plants.

What is a floating type ball valve?

The floating ball valve is a kind of valve that its ball floating inside the valve body; it drifts to the downstream side and would be tightly pushed against the seat by the medium pressure, to ensure a reliable seal. It is a quite simple design with a good sealing performance and relying on the seat material to bear the workload since the sealing stress is mainly imposed on the seat rings. Usually the floating ball valves are working in the pipeline system with a low and medium pressure ratings.
