Metal Bellow Seals are provided in low and high-temperature designs for ensuring to create dry-running seal for emitting containment. They are developed for successfully controlling VOC and VHAP emissions. They are economical and effective solutions of meeting the emission requirements and eliminating the demand for liquid barrier systems. They act as a backup; hence they ensure double safety from leakage during any process. These Metal Bellow Seals can easily withstand the temperature ranging from 400F to 800F. Moreover, they can also work in high pressures conditions up to 300 psi(g)/20 bar(g).
