Class 300 valves have a pressure rating of 300 pounds per square inch (psi) or 20.7 bar, allowing them to withstand higher pressures than Class 150 valves. They are commonly used in industries such as oil and gas, petrochemical, power generation, and refining. Class 300 valves come in various types, including gate valve class 300, globe valve class 300, ball valve class 300, check valves, and class 300 butterfly valve. The material selection depends on factors like the fluid, temperature, and compatibility.

What Is A Class 300 Valve?

A Class 300 valve is a valve that is designed and rated for a maximum working pressure of 300 pounds per square inch (psi). It is classified according to pressure rating standards set by organizations such as ANSI and ASME.

Are Class 300 Valves Suitable For High-Pressure Applications?

Yes, Class 300 valves are designed and rated for higher-pressure applications compared to Class 150 valves. They are suitable for systems that require handling pressures up to 300 psi.

What Industry Standards Apply To Class 300 Valves?

Class 300 valves are designed and manufactured in accordance with industry standards such as ANSI B16.34 for valve design, ASME B16.10 for face-to-face dimensions, and ASME B16.5 for flange dimensions, among others.
