    Y-Type Globe Valve

    Y-Type Globe Valve is designed with an inclined body structure, allowing the fluid flow path to be more streamlined compared with conventional globe valves. It provides lower pressure drop, reduced turbulence, and excellent throttling performance. Widely used in power plants, oil and gas, chemical, and industrial pipeline systems, it is suitable for high-pressure and high-temperature applications requiring reliable flow control and shut-off. With robust construction and reliable sealing performance, the valve offers long service life and stable operation.
