6-150# CF8M Full-Bore Hard-Sealed Swing Check Valve for Long-Distance Pipelines

6-150# 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, 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.

8-150# 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 valve 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 valve 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 maximizing throughput, and 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 involving high‑temperature, high‑pressure piping to prevent backflow, and is suitable for both horizontal and vertical pipeline installations.
