For sale is a NEW, Emergency Shear Valve Dover E-401-1 OPW DIV. 1.125" Inner Diameter of hole. In my opinion this is new because the inner threads of the capped end are very clean and shiny. However, I am not 100% sure. If you receive this item and you don't like it for any reason, you are welcome to return it for a full refund, minus shipping BOTH ways. Thanks.
