About Sanitary Stainless Steel Check Valves / Non Return Valves

Updated: May 17, 2020

Food Grade Stainless Steel Check Valves are used throughout the Malaysian food and beverage industry. This post will provide a basic discussion of the valve.

Disc Check Valve with Ferrule Connections

Sanitary check valves are used in many applications. It normally comes in weld end or ferrule ends, and available in SS 316L, from 1" to 4".

Parts of the sanitary check valve

Check valves allow fluid to flow in only one direction. With pressure, product flows in through one port where a spring loaded disc allows it through, and exit from the other port. Once the disc closes, the product will not be able to return. Sanitary check valves can be installed in vertical and horizontal applications.

Unlike Sanitary Ball Valves and Butterfly Valves, Check Valves work automatically and do not require a person to operate, and can be cleaned by CIP systems. However, Sanitary check valves requires a small amount of upstream pressure to operate, which is called cracking pressure.

While its automatic and simple operating principle makes it convenient to use, sticky products can sometimes cause the valve to not operate properly.

Also, because the disc is always in the way of product flow, there will be a slight pressure drop.
