PTFE and PVDF LINED DAMPERS ARE A DIFFERENT CONFIGIRATION, LARGE DIAMETER WITH SHORT CENTER LINE STROKE, AS SHOWN BELOW, BECAUSE THEY HAVE TO CONTAIN PTFE / FLEXFLON DIAPHRAGMS, GOTO "FLEXORBER" LINED | ||||||||||
ALTHOUGH A PULSATION DAMPER IS SPECIFICALLY NOT COVERED BY ELECTRICAL CONDUCTIVITY REQUIREMENTS OF "ATEC", IT IS POSSIBLE TO CONSTRUCT A DAMPER WITHOUT THE USE OF METALIC BOLTINGS AND WITHOUT THE USE OF METALIC VALVES.. HOWEVER THESE SPECIAL CONSTRUCTIONS REQUIRE THE NORMAL PED AND ISO 9001 APPROACH OF DESIGN VERIFICATION BY TEST TO DISTRUCTION BEFORE RELEASE FOR SALE, WHICH IS A CONSIDERABLE ON COST. | ||||||||||
