2-1500#CF8M Full-Bore Hard-Sealed Swing Check Valve for Long-Distance Pipelines
The swing-type hard-sealed check valve features a rocker‑arm swing‑open design, with the disc pivoting around a pin to open and close. Its sealing surfaces are overlay‑welded with hard alloy, providing excellent resistance to high temperatures, high pressures, and erosive media. When the fluid flows in the forward direction, the disc lifts smoothly to allow unobstructed passage; under reverse flow, the disc closes tightly under the combined action of its own weight and back pressure, ensuring a secure metal‑to‑metal seal. The valve body is designed with a full‑bore configuration, minimizing flow resistance and delivering high throughput capacity. It can withstand harsh service conditions such as high‑temperature steam, oils, and hot flue gases, making it widely suitable for high‑temperature, high‑pressure pipelines in power plants, petrochemical facilities, and metallurgical applications, where it prevents backflow. It is compatible with both horizontal and vertical piping installations.

6-1500# Full-bore hard-sealed swing check valve for long-distance pipelines
The swing-type hard-sealed check valve features a rocker‑arm swing‑open design, with the disc pivoting around a pin to open and close. Its sealing surfaces are overlay‑welded with hard alloy, providing excellent resistance to high temperatures, high pressures, and erosive media. When the fluid flows in the forward direction, the disc lifts smoothly to allow unobstructed passage; when flow reverses, the disc closes under its own weight and the back pressure of the fluid, ensuring a tight metal‑to‑metal seal. The valve body is designed with a full‑bore configuration, minimizing flow resistance and maximizing throughput, and it can withstand service conditions such as high‑temperature steam, oils, and hot flue gases. It is widely used in power plants, petrochemical facilities, and metallurgical applications for high‑temperature, high‑pressure piping systems, effectively preventing backflow, and is suitable for both horizontal and vertical pipeline installations.

10–1500# Full-bore, Hard-Sealed Swing Check Valve for Long-Distance Pipelines
The swing-type hard-sealed check valve features a rocker‑arm swing‑open design, with the disc pivoting around a pin to open and close. Its sealing surfaces are overlay‑welded with hard alloy, providing excellent resistance to high temperatures, high pressures, and erosive media. When the medium flows in the forward direction, it lifts the disc for unobstructed passage; when flow reverses, the disc closes under its own weight and the back pressure of the medium, ensuring a tight metal‑to‑metal seal. The valve body is designed with a full‑bore configuration, minimizing flow resistance and delivering high throughput, making it suitable for service conditions such as high‑temperature steam, oils, and hot flue gases. It is widely used in power plants, petrochemical facilities, and metallurgical applications involving high‑temperature, high‑pressure piping to prevent backflow, and can be installed on both horizontal and vertical pipelines.

Marine cast steel components are produced using ship‑grade, specialized cast steel grades, with melting and casting performed in strict accordance with classification society standards. The resulting castings exhibit a dense microstructure, free from porosity, shrinkage cavities, and cracks. Post‑heat treatment optimizes the metallurgical structure, imparting excellent low‑temperature toughness, seawater corrosion resistance, and fatigue‑load endurance. Our product range includes marine parts such as valve bodies, pump casings, pipeline fittings, and anchoring system components, all meeting stringent dimensional tolerances and delivering reliable pressure‑holding performance. These products pass nondestructive testing and hydrostatic pressure acceptance by major classification societies, making them suitable for pipeline, propulsion, and outfitting applications on both ocean‑going and inland vessels.
