Cash Acme Type F-37 Back Pressure Valve

Got this vintage Cash Acme Type F-37 back pressure valve still in the original box. It's a 1/2 inch pipe size and factory set at 22 PSI. Straight-through diaphragm type design. Box has some wear from sitting around but the valve inside is ready to go if you're doing some plumbing or industrial work. Pretty solid old school quality from Decatur, Illinois. sealed box
