Description
L&T CS Ball Valves are robust, quarter-turn valves designed for on/off and moderate throttling service. Built with precision-engineered components, they offer bubble-tight sealing, low operating torque, and long service life. These valves are ideal for oil, gas, chemical, power, and general industrial applications where durability and reliability are essential.
