DN150 PN25 WCB Swing Check Valve – Flanged Cast Steel Anti-Backflow Valve

This heavy-duty DN150 PN25 Swing Check Valve is constructed from robust WCB Cast Carbon Steel, delivering reliable anti-backflow protection for medium-to-high pressure pipelines. Coated with industrial-grade anti-corrosive epoxy and featuring practical lifting lugs for safe installation, it is perfectly suited for water treatment, steam, and petrochemical systems requiring DIN/EN standards compliance.

🏭 Engineering Highlights:

  • Body Material: ASTM A216 WCB Cast Steel for high impact toughness.
  • Pressure Rating: PN25 (2.5 MPa) for elevated system pressure.
  • Design Features: Bolted cover with lifting lugs (eyebolts) for easy hoisting.
  • Coating: High-build blue epoxy finish for enhanced environmental resistance.
