Cast Iron Flanged PN6 Check Valve - Brass Seat/Disc

This cast iron flanged PN6 check valve provides essential non-return protection for systems operating at lower pressures, offering a cost-effective solution for large-bore pipework. Designed for reliability in utility and gravity-fed networks, it ensures fluid flows in a single direction to prevent backflow damage.

• Connection: PN6 flange (approximately 16 bar nominal rating) specifically sized for larger bore piping systems.
• Body Material: Robust cast iron GJL or comparable, ideal for water or non-aggressive fluid services.
• Seat and Disc Construction: Features a cast brass seat with a cast brass disc for sizes 2" to 4", and a cast iron disc for sizes 5" to 8".
• Operating Pressure: Rated for PN16 (16 bar) performance.
• Temperature Range: Suitable for operation between approximately -10°C to +150°C depending on the specific trim.
• Maintenance: The flanged design allows for straightforward removal and disassembly from the piping system for routine inspection or repair.

Ideal for chilled water distribution and utility water mains where modest system pressure is the norm, this PN6 cast iron check valve delivers practical and reliable performance for industrial applications.
