Sanitary check valves weld type 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 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. It is compact and simple structure for easily cleaning and maintaining without special tools. Our weld hygienic check valves are made in stainless steel 316L or 304, it is your idea choice for the application of food,beverage,biopharmacy etc. Sanitary check valves, also known as "non-return valve", is designed for use in process piping installations to prevent reverse flow.
