I n s i d e Story on POWELL CORROSION RESISTANT VALVES Corrosion resistant valves may appear to be alike on the outside. But inside — in trim materials, in design, in manufacture — there can be a world of difference. And the inside story of Powell Corrosion Resistant Valves is that every valve has PERFORMANCE VERIFIED. The reason there's a big difference in Powell Corrosion Resistant Valves is quality control. It begins not with manufacture — but with the very materials which go into Powell Valves. As a final step of Powell's rigidly enforced quality control, every Powell Valve is subjected to an actual line test. Powell has designed many new types of Corrosion Resistant Valves to meet the needs of the rapidly expanding chemical and process industries. The variety of pure metals and special alloys in which they are available has grown to such an extent that today there is a Powell Corrosion Resistant Valve to control the flow of almost every known corrosive fluid. Consult your Powell Valve distributor. If none is near you, we'll be pleased to tell you about our COMPLETE quality line which has PERFORMANCE VERIFIED.
