clapet anti-retour à double plaque
Description du produit
Wafer shape: It has a flat, disk-like shape so it can be “sandwiched” between two pipe flanges. This makes for easy installation between two pipe sections.
Dual plate design: It contains two circular plates that swing open and closed depending on flow direction. This allows flow in one direction but prevents backflow.
No through flow: The plates completely block flow when they close, providing a tight shutoff against backflow.
Compact size: Compared to swing check valves, china wafer dual plate check valve are more compact in width because the plates swing within a circular body.
Simple design: They typically have few moving parts, making them relatively reliable and easy to maintain.
Low pressure drop: When open, the plates are flush with the pipe interior, causing minimal disruption to flow and pressure.
