Class 300 Bronze Globe Valve
This bronze globe valve adopts Class 300 pressure rating, which enables it to withstand higher working pressure compared with low-class valves.
Class 300 standard defines its strict dimensional and pressure resistance criteria, making it suitable for medium and high-pressure pipeline systems.
Overview
Application：
This Class 300 bronze globe valve features high pressure resistance superior to Class 150 valves, ideal for medium-high pressure piping systems requiring precise flow throttling. It widely serves marine, offshore platform, HVAC steam, water treatment, compressed air and light chemical pipelines with bronze corrosion resistance and Class 300 reliable pressure bearing capacity.
