Description
NIAGARA Check Valve – Models CS5 (PN16) / CS5A (ANSI 125) / CS6 (PN25) / CS5W (PN16)
These models are wafer-type dual plate check valves designed to allow flow in one direction only and automatically close to prevent reverse flow.
The spring-assisted mechanism and rubber seat provide a non-slam operation, eliminating water hammer and ensuring smooth closure.
The EPDM rubber seat enhances sealing and reduces noise during operation, while the compact wafer design makes installation easy between flanges.
Valves of size DN200 and above are provided with eyebolt tapped holes as per BS EN ISO 3226:2010, allowing convenient handling and installation (eyebolts not supplied).
These valves are particularly suited for pump discharge and potable water systems, with WRAS approval for PN16-rated models.
