4A DUPLEX STAINLESS STEEL BALL VALVE

Product Description

Dual phase stainless steel A995 Gr.4A (CD3MN) ball valve is a dual phase steel fixed ball valve, which is made of SAF2205, a995 gr4a, a890 cd3mn or A182 F51 and other major components such as valve body, bonnet, ball, valve rod and fixed shaft. The ball is used as the opening and closing part, and the ball rotates around the center of the valve body to achieve the purpose of opening and closing. The steel used in this valve combines the advantages of austenitic and ferritic stainless steel, It has the ability to resist chloride environment and sulfide stress corrosion, and its strength is about twice that of standard austenitic stainless steel, so it is especially suitable for working conditions with high chloride ion content and sulfide in the medium, so as to cut off, connect, adjust or change the flow direction of the pipeline medium.
