Check Valves

M&H Swing Check Valves are widely specified by engineers and operating personnel. They are well-proportioned and sturdily constructed, and they provide the ideal solution wherever check valves are needed in water and waste-water treatment plants. M&H Check Valves shall be all iron body, bronze mounted, full opening swing type. The valve clapper shall swing completely clear of the waterway when the valve is full open, permitting a “full flow” through the valve equal to the nominal pipe diameter. The Models 59-02 Plain Swing Check Valve, 159-02 Lever and Weight, and 259-02 Lever and Spring all meet or exceed the AWWA Standard C-508, latest revision.
