3″ Check Valve

I posted a 3″ Swing Check Valve on GrabCad today. Within a couple of hours, it got 6 likes and 3 downloads. And if you didn’t know…all downloads on GrabCad are free.

This valve is manufactured by KITZ. It has class 300 raised face flanges and the body is made from cast stainless steel. The face to face dimension is 12.5″.

The KITZ number is 300UOAM3 316SS GRAFOIL C.E.
