OVERVIEW: The economical DD-IW cast iron body, double disc swing lead free check valves use spring assisted half-discs to help keep slamming and surges to a minimum. The wafer style body design is compact and light, and it mates to 150# flanges.
It is suitable for frequent flow reversals, but not fluids with solids. EPDM seats and stainless steel discs. Discs are designed with very low cracking pressure, which reduces the amount of energy needed to open the valve.
For clean liquids.
