Advantages At A Glance

Dual Plate Check Valve	Swing Check Valve
Light Weight thus easier handling and self supporting.	Bulky & voluminous thus cumbersome handling & heavier supporting system.
More compact & structurally sound design.	Large & difficult to analyze from stress concentration points in critical applications due to intricate body shape.
Same valve can be installed horizontally or vertically.	Suitable primarily for horizontal applications.
Only Check Valve which can be installed for flow upside down due to spring assisted closure.	Not possible.
Low Pressure Drop and reduced Energy Loss irrespective of Pressure Ratings.	Significant Pressure Loss and Energy Loss, which is still higher at higher Pressure ratings.
Streamlined flow way.	Swing restricted flow path.
Efficient and Positive sealing under most flow and pressure conditions. Valve closes before flow reversal at zero velocity.	Always require reverse flow for closure and back pressure for effective sealing.
Inherently Non-Slamming. No external devices /attachments required.	External attachment required to counteract slamming.
Water Hammer almost non-existent.	Water hammer tendency persists.
Long life and trouble -free operation.	Seat & Hinge Pin require regular maintenance due to impact loads and wear by rubbing.
