10,000 good turns...all easily done with CHEMIGUMI Quite new in concept is the "butterfly" valve pictured here. It quickly and surely controls the flow of highly corrosive liquids at pressures up to 150 pounds and, in tests, easily survives 10,000 cycles —the equivalent of 20 years' service. Much of the vaive's success stems from the use of CHEMIGUM in its integrally molded seat. CHEMIGUM was chosen because of its easier processing, better bonding and excellent resistance to petroleum products, chemicals, water and wear. How can CHEMIGUM help your product take a turn for the better? Full details are yours by writing Goodyear, Chemical Division, Dept. Q-9416, Akron 16, Ohio.
