Product Overview
The KOZO C95800 Aluminum Bronze Swing Check Valve is designed for seawater, marine, offshore and other compatible corrosive services. The swing-disc mechanism opens with forward flow and closes automatically when flow reverses, helping protect pumps, piping and downstream equipment from backflow.
The reference material is ASTM B148 C95800 nickel-aluminum bronze, commonly used in marine valves, pumps and seawater equipment.
Key Design Features
- Swing-disc non-return design: Automatic operation without an external actuator.
- C95800 body: Nickel-aluminum bronze construction for marine and compatible corrosive service.
- Flanged ends: RF reference configuration for industrial piping systems.
- Renewable internal parts: Seat/disc arrangements can be selected according to the project specification.
- Horizontal installation: Typical configuration for conventional swing-check operation.

Seat and Disc Options
Metal and resilient sealing configurations may be available depending on size, pressure class and service. Elastomer seat temperature limits must be checked against the actual material rather than using the metal-body temperature range.
Selection Notes
C95800 is widely used in marine service, but final suitability still depends on water chemistry, velocity, temperature, deposits and the complete valve material combination.
How to Specify This Valve
Please provide size, pressure class, medium, design pressure, temperature, seat/disc configuration, end connection and quantity.
FAQ
Does a swing check valve need an actuator?
No. The disc opens and closes automatically according to flow direction and differential pressure.
Can the valve use an NBR seat?
Resilient-seat options may be available, but the allowable temperature must be based on the selected elastomer and actual operating conditions.
