Stainless Steel Sanitary Welded Union Non Return Check Valve

The sanitary check valve is a universal one-way fluid valve. It is light in weight, small in size, and easy to install between flanges. The inside of the valve is composed of two semicircular springs and a plate surface. The spring is fixed on the valve body with a pin to close the valve plate and the fluid pressure opens the spring. The deformation is very fast, which can protect the pipeline from water hammer damage.
