Xomox Lined Plug Valves
Features and benefits

Locked in Liner

The melt processible PFA or
FEP liner is locked into cast
grooves, machined slots, and
cast holes in the body and plug
castings. This helps prevent
liner collapse in vacuum
conditions and blow out in high
pressure conditions in
conjunction with high
temperature.

Cavity-free design
Cavities are absent in open
and closed positions. This prevents accumulation of particulate
matter and makes the valve ideal for slurry applications.

Large seal area
The seal is created by the interface between the plug and the body
liner. The outside of the plug and the inside of the body cavity are
at a 2
กใ taper. The wedge action results in a tight shut-off. Because
the seal is created due to compression, the valve is bi-directional
and seals on both, upstream and downstream sides.

Double atmospheric seal
The primary seal is between the plug and body liner. The secondary
seal is an inverted V-lip arrangement which is pressure assisted.
This ensures excellent seal to atmosphere.

In-line adjustment
The three adjustment bolts in the top cover can be utilized to
improve in-line sealability. These bolts have to be tightened in
order to push the plug down and create a tight shut-off. Downtime
can be drastically reduced.
