Hygienic Grade Stainless Check Valve One Way Flow Direction For Water Pipelines
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.
Sanitary Check Valve is the sanitary valves worked to prevent the flow from reversing. It is made in stainless steel AISI 316L or 304, with the adavantages of smooth surface, seamless, automatic emptying and easy to maintain etc. Sanitary check valve is also applied to steam and self-cleaning requirement, it is a good choice for the application of food,beverage,biopharmacy etc. With different connection ends, sanitary check valve from NYHAU assures you a safe, easy, fast pipeline.
