OVERVIEW: The SS-DW ductile iron swing check valves is a Class 150# economical design with low weight and short laying length that saves initial cost, space, and installation time when compared to a full body swing check valve. Head loss is minimized with a short, straight, and unobstructed flow path. And the spring-loaded disc is designed with very low cracking pressure to reduce the amount of energy needed to open the valve.
The SS-DW features anti-corrosive, stainless steel trim, with a field replaceable Buna-N soft seat to ensure a bubble tight seal that meets or exceeds API 598 est requirements.
Acceptable for wastewater.
