Cast Iron Check Valve – Flanged PN6

For systems operating at lower pressure but still requiring large‑bore check functionality, this cast‑iron flanged PN6 check valve provides non‑return protection in a budget‑friendly format.

Technical Data:

• Connection: PN6 flange (approx. 16 bar nominal rating) sized for larger bore pipework

• Body: Cast iron GJL or comparable, suited for water or non‑aggressive fluid service

• Seat/disc construction: Cast Brass Seat, Cast Brass Disc 2" to 4", Cast Iron Disc 5" to 8"

• Operating pressure: PN16 ( 16 bar )

• Temperature range: Roughly -10 °C to +150 °C depending on trim

• Typical application: Utility water mains, gravity‑fed networks, chilled water distribution where low pressure is the norm

• Maintenance: Flanged design enables direct removal/disassembly from piping system for inspection or repair

Summary:
Where system pressure is modest but non‑return is still essential, this PN6 cast‑iron check valve offers a practical, large‑bore, flanged solution with basic but reliable performance.
