Silence check valve

Features:

Space of the valve cavity employs streamlined design,overcoming turbulent flow of the media. the spherial  structure at the front part of the discs and bevelled sealed surface reduce impacts on medias and also the flow-resistant coefficient.The inner guide vane adoptes a style of thin eggshell so as to ensure the flow of the media unblocked.At the same time,the weight of the valve reduces as well. A largest flowing sectional area is created by reasonably lifting the height and enlarging the inner space,which also effectively avoid the produce of an air-chamber,upgrade the  valves Cv value and overcome noise.

Application

The two kinds of valves are widely used in heating systems and industrial water supply and drainage systems
