High Pressure Self-Sealing Valve Packing, Graphite, 20*30 mm

The High Pressure SelfSealing Valve Packing Plant produces a low emission packing set that meets ISO 15848 standards. This set includes 7 rings made from graphite, reinforced with metal wire, ensuring durability and reliability under highpressure conditions. With an inner diameter (ID) of 20 mm and an outer diameter (OD) of 30 mm, it is designed to operate at a maximum pressure of 25 MPa. The packing set is selfsealing, which enhances its sealing performance and reduces the risk of fugitive emissions.
