AAP Cast Steel Flanged Globe Valve, 2"

This AAP cast steel flanged globe valve has an ASTM A216 WCB body, a Stellite faced seat ring and ANSI Class 300 flanges. It is supplied in 4 sizes from 2" (50mm) to 4" (100mm). A globe valve regulates flow with a movable disc that closes down onto a stationary ring seat inside a roughly spherical body. Flow turns through the body, so a globe valve has a higher pressure drop than a gate valve of the same size.

The maximum working temperature is 440°C and the cold working pressure is 5,100 kPa (51 bar), with design to ANSI B16.34, flange dimensions to ANSI B16.5 and face-to-face dimensions to ANSI B16.10. The pressure figure is the cold working pressure, so the allowable pressure falls as the temperature rises. The body is ASTM A216 WCB, the seat ring is A105 with an ER CoCr-A (Stellite) hard facing, the bonnet gasket is 13Cr and graphite, the packing is graphite and the handwheel is ASTM A356.
