10 Inch Class 1500 WCB Pressure Seal Swing Check Valve, Butt‑Weld End

This 10‑inch Class 1500 pressure‑seal swing check valve adopts butt‑weld ends, valve body material WCB carbon steel. It is manufactured strictly in accordance with BS1868 standards.

The unique pressure‑seal bonnet design can maintain excellent sealing effect under ultra‑high‑pressure environments, effectively preventing fluid back‑flow in the pipeline. Butt‑weld connection greatly improves connection strength, ensures stable zero‑leakage operation for a long time under heavy‑load working conditions.

The valve is widely used in thermal power plants, petrochemical, oil‑gas and other critical high‑pressure pipeline systems, applicable for steam, water, oil and other non‑corrosive media. We support customized materials, sizes and technical parameters to satisfy different project requirements.
