Structural features:
TS 308-AV-6 consists of a rectangular cross-section packing ring pressed with special graphite fiber braided packing.
Application scope:
The unique structural design and manufacturing process allow TS 308-AV-6 to be installed behind the valve. Even under harsh conditions such as ultra-low temperature, high temperature and high pressure, the valve stem can still maintain zero fugitive emissions after thousands of reciprocating movements, achieving an ideal sealing effect.
