PureFlex – 200 Series Swing Check Valve

General Details

The 200 Series valve is a full face wafer design that conforms to ISO 9001 standards and ANSI B16.5 Class 150. They are built to be corrossion resistant and can unseat with less that 1psig of pressure. It can also seat itself without any flow, in both horizontal and vertical lines.

To conform to the rigid PureFlex standards, each valve is hydrostatically shell tested at 1.5x its rated cold working pressure for 3 minutes to ensure the best construction. They are then seat tested at 20psig and 1.10 x rated shutoff to ensure no leaks are found.
