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 technical parameter:

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. 2. The closing part (gate) adopts an elastic structure, which can
