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

This 14‑inch Class 1500 pressure seal swing check valve with butt‑weld ends is cast from WCB carbon‑steel, manufactured in compliance with API 6D, ASME B16.34 standards.

The pressure‑seal bonnet structure provides superior sealing performance under extreme high‑pressure working conditions, effectively preventing medium back‑flow inside the pipeline. Butt‑weld connection guarantees high structural strength and zero‑leakage for long‑term heavy‑duty operation.

Widely used in thermal power plants, petrochemical, oil & gas and other critical high‑pressure piping systems, suitable for media including steam, water, oil and non‑corrosive fluids. Custom materials, sizes and technical specifications are available upon request.
