High Sanitation Stainless Ball Check Valve , Hygienic Check Valves For Water

Stainless steel sanitary ball check valves are widely used for both sanitary and industrial applications to prevent backflow of product.

Type: Ball Check
Sizes: 1 1/2" - 3"
End Types: Clamp - Weld
Grades: 316L

Sanitary check valve also known as one-way valve, its role is to prevent the pipeline water back in the media. Are different to many other types of valves, for check valves work automatically and most are not controlled by a person or any external control. Accordingly, most do not have any valve handle or stem. Thus there is an important concept in check valves, it is, the cracking pressure. Cracking pressure is the minimum upstream pressure at which the valve will operate. So the check valve is designed for and can therefore be specified for a specific cracking pressure.
