CHV101-125
MSS SP-71 Class 125 Cast Iron Swing Check Valve is a cast iron swing check valve that complies with the American Standard Manufacturing Society (MSS) standard SP-71 and is rated Class 125.
Introduce: MSS SP-71 Class 125 Cast Iron Swing Check Valve is commonly used in piping systems to prevent backflow of media in the pipeline while allowing one-way flow. It is made of cast iron and has a swing-type valve cover to ensure the correct direction of fluid flow.
Prevent backflow: Prevent the backflow of media in the pipeline by automatically closing the valve to protect the pipeline system and related equipment.
Reduce water hammer: Effectively reduce water hammer caused by medium backflow and protect the stability and safety of the pipeline system.
Economical and affordable: Valves made of cast iron are lower in cost and are an economical choice for general industrial applications.
Usage: MSS SP-71 Class 125 Cast Iron Swing Check Valve is mainly used in industrial piping systems, including water supply systems, cooling water systems, chemical plants and pharmaceutical industries. By preventing backflow and water hammer, the valve plays an important role in industrial piping systems, ensuring the safe, stable and reliable operation of the piping system.
Cast iron material: The valve body is usually made of cast iron, which has good strength and corrosion resistance.
Swing-Type Valve Cover: Featuring a swing-type design that opens easily and holds the valve open to allow one-way flow.
Class 125 standard: Complies with the Class 125 requirements in the MSS SP-71 standard and is suitable for general industrial applications.
