Coatings and Rubber Linings Withstanding Harsh Conditions and the Test of Time In many industrial facilities, valves are reg u lar ly subject ed to harsh conditions, in clud ing re cir cu lat ing wa ter loops where cor ro sive ness in creas es each time the water pass es through the sys tem, and cooling water sys tems which utilize brack ish wa ter or salt wa ter as a me di um. This is especially true at fossil and nu cle ar pow er gen erating plants, which fre quent ly use sea water as their main cooling wa ter resource. To com bat the damaging effects of these harsh condi tions, Pratt utilizes epoxy coatings and rub ber linings in conjunction with superior design fea tures to help ensure that the Triton XR-70 butterfly valves will withstand the test of time. The unique construction of the Pratt Triton rub ber seated butterfly valve makes both epoxy coatings and rubber lin ings much more ef fec tive than other butterfly valve de signs. Since all surfaces of the Triton disc are exposed, there is no possibility for corrosion to start in hidden, un pro tect ed areas like the inside of a hollow, lens-shaped offset disc. Since there is no seat retention hardware, coating and/or lining breakdown in this area is also elim i nat ed. Rubber Linings Pratt lines corrosion-susceptible surfaces with a 3 ⁄16-inch thick rubber of 60 Shore A durom e ter. The surfaces are prepared and blasted to a near- white metal finish. The linings are ap plied by the “hand-lay-up-meth od” (similar to tank lining techniques) and then cured in an open steam autoclave using 40 to 50 psig steam pres sure. Following application and curing, the linings are vi su al ly inspected for air bubbles and checked at 7,000 volts with a positive control high-volt age spark tester. Epoxy Coatings Pratt has an extensive coating facility which ap plies and cures coatings in a controlled en vi ron ment. Prior to ap pli ca tion of the epoxy, valves are sand blast ed and thoroughly cleaned to ensure a prop er bond. The in te ri or and external sur fac es of each valve are coated with a Polya mide-cured, rust inhibiting epoxy, NSF ap proved. A mag net ic dry film thickness gauge is used to con firm that the coat ing thick ness match es the project/or der spec i fi ca tion re quire ments. Electron ic test ing for pin holes (hol i days) is per formed. In applications involving salt water and/or en trained sol ids which can cause erosion, the su pe ri or i ty of rubber lining on the valve disc has been clearly demonstrated by Pratt but ter fly valves placed in service decades ago that are still providing bubble tight closure today. Both ep oxy coat ing and rub ber lin ing have also suc cess ful ly pro tect ed the valve bodies in these corrosive ser vice con di tions as illustrated by Pratt’s long track record of quality and re li abil i ty at in dus tri al facilities and power plants around the world. 3/16" RUBBER Other rubber lining features include Pratt’s shaft-bearing being thor ough ly pro tect ed by rubber shaft seals to maintain bearing performance throughout the life of the valve. Also, the shaft bore in disc is sealed with a rubber seal. The juncture of the rubber liner to the rubber seat is also protected by a sealant applied under pressure. LINING CORROSION-RESISTANT DISC EDGE LINING Complete coverage of corrosion susceptible wetted surfaces is demonstrated in these drawings. Body lining in conjunction with the seat creates a water barrier and protects against corrosion. Henry Pratt Company | 7
Water Flow Characteristics Proven Performance During its product development phase, the Triton butterfly valve was test ed to en sure that it met our own rigorous standards for flow ca pac i ty. The Tri ton but ter fly valve con sis tent ly pro duced high C v values which trans lates to low er flow re sis tance, in turn, low er ing system operating costs to the user over the life of the valve.
