Rupture Discs/Relieve Valves


Relief valves are an important component for preventing excessive pressure build-up in an extruder. If the valve stem is too long, however, polymer may freeze-off, preventing the valve from functioning properly. At DuPont, we cut off the stem just beyond the barrel, leaving just enough to get a wrench on it for removal.
