Description
NIAGARA Check Valve – Model CS4 / CS4 ANSI
The CS4 and CS4 ANSI models are swing-type check valves engineered to ensure smooth one-way flow and automatic closure to prevent backflow.
Designed for flow velocities up to 3 meters per second, these valves are ideal for water and other non-corrosive liquids.
They feature a bolted cover for easy maintenance and are suitable for installation in both horizontal and vertical pipelines.
Constructed from durable cast iron, the CS4 valves offer exceptional strength, reliability, and long service life under varying temperature and pressure conditions.
Both models comply with international flange standards, providing compatibility across different piping systems.
