A large bore full-welded ball valve is a ball valve with a full-welded structure, specifically designed for handling high flow rates and high-pressure fluids, with diameters typically over 2 inches. It controls the flow by rotating the ball, featuring high-pressure resistance, corrosion resistance, and reliable sealing. It is widely used in industrial pipeline systems for oil, gas, water supply, and more.

Structural Features

A fully welded structure eliminates the risk of leakage caused by traditional threaded or flanged connections. All components (such as the ball, valve seat, and stem) are assembled through precise machining, ensuring the valve maintains its sealing performance under high pressure and temperature variations. The optimized body design reduces flow resistance and enhances the accuracy of flow control.

Application Scenarios

Ideal for oil & chemical industries, natural gas transmission, urban gas pipelines, power plant circulating water systems, and wastewater treatment, capable of withstanding high temperature and pressure environments, ensuring stable fluid transmission.

Installation Precautions

Before installation, check if the valve holes are clean to avoid foreign objects affecting the sealing performance; ensure the valve is open before welding to prevent slag from entering the valve body; wait for the valve to cool down before operating after installation.
