Primary stem seals are formed by preloaded contact between the disc and seat. A secondary seal is effected by having a steam diameter greater than the stem hole in resilient seat. These seals provide a non-wetted body and stem, eliminating the need for corrosion resistant body material.
Field replaceable, phenolic bonded cartridge is blowout proof, stretch resistant and non-collapsible, making it an ideal seat design for high velocity of vacuum service. Our resilient seat design eliminates the need for flange gaskets.
Accurate and smooth machined profile of disc edge requires minimal deformation of the resilient elastomer liner to achieve a positive seal. The low deformation results in low torque, less wear of the seat liner and increased operational life.
