Are different to many other types of valves,for Hygienic 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 Food Grade Check Valves is designed for and can therefore be specified for a specific cracking pressure.

Sanitary Check Valves Weld type is a butt weld connected Hygienic Valves , a general type of sanitary check valve.
