[ dual plate check valves v swing check valves ] [ swing check valves beware ]
 
The full bodied swing check has existed for centuries and its technology has changed little in that time. It is rapidly being superseded by the Dual Plate Check Valve as the check valve of choice.

Here are 2 extracts from Mr. Ron Merrick’s article in the August 1998 issue of the Valve World magazine:

“The double door check valve is now the dominant valve in the hydrocarbon and chemical industries”

“The vast majority of process industries now use the double door check valve as the valve of choice”.

Ron Merrick is Director, Piping Materials Engineering with Fluor Daniel Houston. Widely respected and world-renowned, he is the author of the book “Valve Selection and Specification Guide” published by Van Nostrand Reinhold, 1990 (currently out of print).
