Class 300 Globe Valve
All Class 300 valves require a seal test. The test pressure is typically 1.1 times the rated pressure at 100°F using water. For valves of specific specifications, an air tightness test at 80 psi may be substituted for the water pressure test.
Overview
Introduction:
The construction of a Class 300 Globe Valve typically involves robust materials to withstand the high pressures associated with its rating. Common materials for the body, disc, and seat of the valve include stainless steel, carbon steel, and alloy steel, chosen based on factors such as fluid compatibility, temperature, and pressure requirements.
