Dual Plate Wafer Check Valve Features
Compact design, lightweight, easy to maintain.
Two torsion springs are used to ensure quick and automatic closing of the valve plates.
Fast closure prevents backflow and reduces water hammer effect.
Short length provides rigidity and ease of installation.
Easy to install on horizontal or vertical pipelines.
Tightly sealed with no leakage under pressure testing.
Safe and reliable operation with strong interference resistance.
Flange connection dimensions conform to GB4216-84 and GB4216.5-84 standards.
Face to face dimensions follow ISO5752-82. The stem should be perpendicular to the horizontal level when mounted on a horizontal pipeline. For vertical installation, the flow direction should be downward.
