Product Description
The DFT Excalibur NAB is a flanged silent check valve built in nickel-aluminum bronze, combining DFT's spring-assisted slam-free closing design with the seawater-resistant NAB material used on the GLC NAB elsewhere in this range.
This combination suits marine and offshore pump discharge lines where both corrosion resistance and slam-free closure are required. Exact size and pressure rating are not listed in our current data — confirm these with our technical team.
