Product Overview
The KOZO Monel 400 Swing Check Valve is designed for marine, seawater and selected corrosive process systems requiring automatic backflow prevention and nickel-copper alloy construction. Forward flow opens the disc; reverse flow causes the disc to return toward the seat.
Why Monel 400?
Monel 400 / UNS N04400 is widely used in marine and selected chemical environments. Its performance depends on water chemistry, flow velocity, temperature, deposits and galvanic coupling, so it should not be described as immune to all seawater corrosion.
Key Design Features
- UNS N04400 / Monel 400 pressure-containing construction.
- Swing-disc automatic non-return function.
- Flanged or butt-weld connection options.
- Project-specific disc, hinge and seat materials.

Selection Notes
Check-valve performance depends on installation orientation, flow velocity and minimum opening flow. Material selection should also consider stagnation and galvanic conditions.
