1. Ductile Iron valves offer higher pressure ratings than Cast Iron. valves For example, Ductile Iron valves (2" ~ 24") are rated at 250 psi wog. By comparison, Cast Iron valves (2" ~ 12") are rated at 200 psi wog and (14" ~ 24") are only rated at 150 psi wog.

markets : general industry , chemical , petrochemical , power , and food & beverage service : intended for liquid service that is steady , clean ( no abrasives or solids ) and non - pulsating . flow rate should not exceed 15 ft / sec . not recommended for steam or reciprocating compressor service . buna - n properties : most widely used elastomer . good for most petroleum oils and fluids , silicone greases and oils , and cold water . excellent compression set , tear , and abrasion resistance . poor weather resistance and moderate heat resistance . not recommended for severe ozone - resistant applications .

The above data represents common market and service applications. No representation or guarantee, expressed or implied, is given due to the numerous variations of concentrations, temperatures and flow conditions that may occur during actual service.
