Description
L&T Ball Valves are designed for tight shut-off and quick quarter-turn operation. They provide bubble-tight sealing and are ideal for handling oil, gas, steam, water, and corrosive fluids. Available in floating and trunnion-mounted designs, these valves ensure long life and low torque operation, even in high-pressure and high-temperature applications.
