carbon steel butterfly valve Description
Carbon steel butterfly valve is a butterfly valve made of carbon steel (such as ASTM A216 WCB, A105, etc.) as the main material. It realizes the opening, closing and regulation of the fluid by rotating the butterfly plate. Its core components include carbon steel valve body, disc valve plate, valve stem and sealing system. It is suitable for medium and high pressure and non-corrosive media scenarios, and has both economy and reliability.
Core advantages
High strength and pressure resistance
Carbon steel material has excellent mechanical properties and can withstand pressure ≤16MPa and high temperature ≤425℃, which is suitable for high-load conditions such as petroleum refining and power boilers;
Surface treatment processes (such as epoxy resin coating and hard alloy surfacing) improve corrosion resistance and wear resistance and extend service life.
Economy and easy processing
The manufacturing cost is 30%-50% lower than that of stainless steel valves, which is suitable for medium and large projects with limited budgets;
Support casting, forging and welding processes, and flexibly adapt to non-standard pipeline requirements.
Low flow resistance and compact structure
The butterfly disc design makes the flow resistance coefficient (Cv value) close to 85% of the same diameter ball valve, suitable for large flow medium control;
The valve body thickness is 40% less than that of the gate valve, saving installation space and reducing the complexity of the pipeline system.
