In the unique EVERLASTING Valve, the disc never leaves the seat, even when the valve is full open. The disc moves across the sealing surface with a rotating motion, thus regrinding one to the other. Therefore, this self-grinding movement of the disc across the sealing faces, each time the valve is operated, continuously polishes the sealing faces, with the result that the sealictually improves with use. This feature, coupled with the fact that the BVERLASTING Valve is quick-act ing, easy to operate, and drop-tight, makes it the ideal valve for many services. For more than 40 yean, the simple, Sturdy construction and ingenious me chanical principles of the EVERLAST ING Vilve have built up an enviable reputation for dependable trouble-free operation, long service life, and low maintenance expense. These valves are widely used through out industry, and are in particular demand wherever quick and easy operation, leakproof closure, and thorough reliability are important when handling fluids such as steam, water, oil, acids, alkalies, process liquids, air, etc. EVERLASTING MUves are made in a range of sixes for various pressures, and are available in a variety of operating arrangements for greatest convenience in the individual installation.
