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. |

-
Silent shut-off is achieved via the fully
automatic, spring-assisted, double-guided disc
that closes near zero flow velocity
-
Short travel distance 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
