- Duvalco Swing Check Valves combine robust engineering with reliable performance.
- Each valve features a lever, weight, and protective cover to ensure smooth, dependable operation.
- The durable ductile iron body delivers long service life, while the precision seal makes it ideal for clean water applications.
- Its streamlined design prevents backflow and reduces water hammer, protecting your system from costly damage
Characteristics
- We coat all internal and external cast surfaces with fusion-bonded powder epoxy at a minimum thickness of 250 μm DFT.
- Moreover, the WRAS-listed epoxy ensures safe use in potable water applications and meets BS 6920 water quality testing standards.
- In addition, our bonnet-mounted shaft design allows technicians to perform maintenance without removing the valve from the pipeline.
- Finally, we apply colour coding for easy identification—blue RAL 5005 for potable water and red RAL 3001 for fire hydrant systems.
Key Benefits of Swing Check Valves in Water Applications
