Material Advantage for Corrosive Environments
Cast Steel Body
Constructed from high-strength cast steel, offering exceptional pressure-bearing capacity and impact resistance, making it suitable for long-term operation in industrial piping systems.
Single Disc Design
The single-disc structure ensures flexible opening and closing, effectively mitigating water hammer shock and enhancing check valve stability.
Bolted Bonnet
The bolted bonnet structure provides a reliable seal and facilitates subsequent maintenance as well as the replacement of internal components.
RF Flange Connection
The RF (Raised Face) flange connection method ensures stable sealing performance and is compatible with standard industrial flange systems.
Epoxy Coating
The surface features an RAL5005 epoxy coating, enhancing corrosion resistance, rust prevention, and weatherability.
