Part Numbers for Bonnet Уплотнение Carriers for U, UM and U II ПВО’s

The bonnet seal carrier is a bore-type sealing assembly which replaces the face seal used as the previous bonnet seal. Sealing capability is not dependant upon bonnet bolt torque. One seal is captured in a machined bore in the ПВО body while the other seal is captured in a machined bore in the intermediate flange.

The seal carrier was designed, developed and performance-verified for use in newly manufactured ПВО’s or as a replacement seal assembly for ПВО’s where either the ПВО body or the intermediate flange requires weld repair
on the sealing surfaces.
