Valves are designed to control and regulate liquids (such as water and oil) and gases (such as air and vapor) that travel through pipe systems. Kubota offers valves for use in a broad spectrum of fields, including water supply and sewerage infrastructure, as well as the agriculture and fishery, steel, petrochemical and energy industries. With diverse models, configurations and structures available, Kubota's valves are designed for different purposes and applications. For example, all-rubber-lined butterfly valves are used in large power generation plants to circulate water, or in seawater pipelines. Resilient seated gate valves are designed to stop water flow in different segments of water supply networks. Metal-seated ball valves for city gas are used in city gas pipelines, where safety has top priority.
