Performance:
• The innovative Dual-Plate Design employs two spring-loaded plates suspended on a central vertical hinge
. As Flow Begins, the plates open in response to a resultant force Which acts at the center of the sealed Surface Area
• The Contact point of the reacting spring leg's force acts beyond the center of the plate area, causing the heel to pen first. This prevents rubbing of the seal surface prior to normal plate opening
• As the velocity of flow decreases, torsion spring action reacts automatically. The moves of plates closer to the body seats, reducing the distance and time of travel for closure. By Having
. the plates closer to the body seats at the time of flow reversal. The valve dynamic response is greatly enhanced, This dramatically reduces the water hammer effect
• At closing, the point of spring force causes the plates to close first. This prevents dragging of the heels of the plates and periods maintains seal integrity for much longer Periods
