|| The seat is a derivative of TB-D1 and TB-E1 seats. The seat consists of a high-performance anti-pressure explosion (AED) elastomer seal ring and a sphere, which is installed in the metal base to form a sealing pair, and then the metal plug-in limit is pressed.
||Metal plug-in isolates particulate matter and protects elastomeric sealing ring. Metal plug-in is wear-resistant and erosion-resistant, and its structure is firm and stable.
|| This structure is recommended to be used in medium and low pressure medium and small caliber gas-containing medium with frequent opening and closing. The recommended dimensions of Tengbo are DN50-DN150, pressure grade PN16-PN63, Class150-Class400.
