The L&T Carbon Steel Valves can come in different types such as control valves, check valves, unidirectional valves and bidirectional valves. The applications such as water management, wastewater treatment, pollution control, oil and gas, pharmaceutical and petrochemical industries all use the L&T Gate Valves and other types. The branded gate valves operate with metal or high alloy gates inside the valve body to regulate the fluid flow through the body. The material for the gate can be chosen according to the fluid flowing inside the valve. The L&T Globe Valves are used in low flow systems. These valves do not excerpt much water hammer effect on the pipeline or liquid.
