A gate valve refers to a valve in which the closing element (gate disc) moves vertically along the centerline of the passage, primarily used for pipeline interception. As a widely applied valve type, gate valves are only suitable for full-open or full-closed control of pipelines and cannot be used for regulation or throttling.
Cast steel is mainly used to control the flow rate, pressure, and temperature of pipelines in industrial automation scenarios, with applications in fields such as power, metallurgy, petrochemicals, environmental protection, energy management, and fire protection systems.

Product description:
1. Compact structure, small size, good rigidity, and safe and reliable sealing.
2. The closing part (gate) adopts an elastic structure, which can automatically compensate for valve body deformation
caused by abnormal loads or temperatures during operation, ensuring reliable sealing without generating gate wedge
columns.
3. For manual valves with a nominal diameter greater than or equal to NPS10" and a pressure class of 150 lb, as well as
those with a nominal diameter greater than or equal to NPS6" and a pressure class of 600-2500 lb, the operating devices
are equipped with rolling bearings for easy opening and closing.
