Non-Return Check Butterfly Valves for Nuclear Applications
Cooling water and flow control with a nominal diameter reaching up to 4000mm
Introducing our advanced Butterfly Valves and Non-Return Check Valves, designed for nuclear applications. Adhering to international standards, these valves offer a tight closure in both flow directions, multiple drive options, and counterweight actuation support. Made from Carbon Steel, Stainless Steel, and Nickel Aluminium Bronze (NAB), they resist corrosion and cavitation. Ideal for outer cooling water circuits, sea or river water, hot water/steam, process water, and liquids with soft sealing up to 120°C. Experience reliability and flexibility with our valves.
Material
- Carbon Steel, Stainless Steel.
- Nickel aluminium bronze (NAB) is widely used in seawater systems, particularly as cast valve bodies & internals.
- Corrosion resistance of the alloys relies on a complex copper-aluminium thin adherent oxide surface film, which acts as a protective barrier and is self-repairing
Applicable standards
- Outer cooling water circuit (Nuclear)
- Sea or river water
- Hot water/steam
- Process water
- Liquids with soft sealing up to 120°C
