The Pratt® Tilting Disc Check Valve is the most versatile and reliable check valve Pratt has to offer.
This valve offers significant energy and cost savings over the life of the valve due to its large flow area and low head loss characteristics. Short disc travel from full open to full close provides the ability to close very rapidly or very slowly to avoid contributing to slamming and surges. The tilting disc check valve is also offered with an upper hydraulic dashpot to aid in disc closure in multiple pump systems even after a power failure. Henry Pratt continues to expand our product offering to those customers who require specialty valves for applications where opening and closing times are critical to control flow reversal and reduce water hammer.
