produces an efficient effect of dynamic pressure during rotation, which maintain optimum clearance between the seal faces in order to minimize the leakage. Thanks to the dual-directionality this seal makes the installation arrangement work more economical for a wide range of applications. Furthermo

โฆ Synopsis
Dynamic sealing
serves as a non-permeable sealing mechanism with rebound capabilities.
The packin~ can withstand up to 6000ยฐF in non oxidising conditions, 4500 psi steam and pH from 0 to 14, except for strong oxidisers such as nitric and oleum.
Marlo says that in the past in order to achieve this level of protection, end users had to die cut packing, which because it had to be formed lot each valve is more costly and time consuming. The Style 396 is a non-customised design however, allowing it to be l~tbricated in an off the-shelf bulk manul~mturin K process.
