Note :-

* Backseat and Stem only applies to Gate and Globe Valves.

For Swing Check Valve, Trim material includes Hinge Pin material which will take reference from stem material.

* HB (formerly HBN) is the symbol for Brinell Hardness per ASTM E10.

* Body and gate seat 250HB minimum, with 50 HB minimum differential between body and gate seat surfaces.

* Manufacturer's standard hardness.

* Differential hardness between the body and gate seat surfaces is not required.

* Hardness differential between body and gate seat surfaces shall be manufacturer's standard.
