AAP Cast Steel Flanged Check Valve, 2"

This AAP cast steel flanged check valve has a WCB (ASTM A216) body and bonnet, a 410 (2Cr13) disc, a Stellite seat and ANSI Class 150 flanges. It is supplied in 8 sizes from 2" (50mm) to 12" (300mm). A check valve lets fluid flow one way and closes against reverse flow, which protects pumps and equipment upstream.

The maximum working temperature is 300°C and the cold working pressure is 1,960 kPa (19.6 bar), with design to ANSI B16.34 and flange dimensions to ANSI B16.5. The pressure figure is the cold working pressure, so the allowable pressure falls as the temperature rises.

Where this product is used

• Preventing reverse flow on hot and high pressure flanged lines
• Process and utility pipework in steel flanged systems
• Pump discharge lines in steel pipework
