Available in Sizes Up to 12 Inches

GF Piping Systems” Type 369 wafer check valve is available in sizes as large as 12 inches. Suitable uses include aquatics, chemical processing, municipalities, water and wastewater treatment, and water parks. Check valves, used to allow flow in one direction, typically require glue or tools for installation. The Type 369 check valve eliminates such requirements, as it can be inserted between two standard ANSI or ISO/DIN flanges. Centering eyelets simplify fitting and installation. A good fit for applications requiring horizontal mounting rather than standard vertical mounting where gravity is present. A spring option in either 316 SS or Hastelloy C enables horizontal position. The valve features a PVC body and EPDM or FPM seals. A specially designed sealing Q ring makes it compatible with flat or serrated flanges.
