✦ Synopsis

Dynamic sealing

serves as a non-permeable sealing mechanism with rebound capabilities.

The packin~ can withstand up to 6000°F 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.
