The KTN 531 is an updated version of the check valve with a cast CF8M stainless steel body and classes available in 150/300/600/1500 , ANSI flanges .
Thanks to the presence of molybdenum [Mo] in the alloy, we have dramatically improved the resistance of the steel to corrosion , also preserving the natural mechanical resistance of the steel stainless and high temperatures . This alloy gives the valve the ability to work with corrosive acids such as sulfuric, hydrochloric, phosphoric and nitric.
The presence of this material is very common in the food, chemical and pharmaceutical .
