Floating ball valve pvc 4 inch is a type of ball valve in which the ball is not fixed in position and is free to move as the fluid flows through the valve. This design provides low torque and easy operation. Floating ball valves have a simple structure consisting of a valve body, a ball, and a stem. The 4 inch pvc ball valve is held in place by two seats at each end of the valve body, which seals the flow path when the valve is closed.Floating ball valves are widely used in various industries, including oil and gas, chemical, water, and power generation. They are ideal for high-pressure and high-temperature applications, as well as low-pressure services.The major advantage of a floating ball valve is its ability to provide tight sealing even under severe operating conditions. The 4 inch plastic ball valve also has low pressure drop across the valve and requires minimal maintenance.
