Ductile Iron check valves offer higher pressure ratings than Cast Iron check valves. For example, Ductile Iron check valves (2" ~ 24") are rated at 640 PSI WOG. By comparison, Cast Iron check valves (2" ~ 12") are rated at 500 PSI WOG and (14" ~ 24") are only rated at 300 PSI WOG. |

| Features:
Silent shut-off is achieved via the fully automatic, spring-assisted, double-guided disc that closes at zero flow velocity
-
Short travel distance (approx. 1/4 of valve size) and quick closure of the disc eliminates water hammer by creating a positive shutoff prior to flow reversal
-
Head loss is minimized by providing a large cross- sectional area which exceeds that of the adjacent pipeline
-
Ductile iron body maintains the anti-corrosive properties of cast iron while achieving a yield strength comparable to carbon steel
-
Can be installed in any position (horizontal or vertical with upward flow) - consult factory for vertical with downward flow
-
Certain sizes allow direct mounting of a wafer type butterfly valve to the outlet end without requiring a space flange or spool piece
