Expanding Gate Valves
That is why you find them in a wide range of critical
applications, from pipelines to power plants, in ESD
and other demanding isolation applications.
The Model EG valve provides a superior bi-directional
mechanical seal because the two-piece gate assembly
expands against the seating areas in the open or
closed position. The greater the torque, the tighter the
seal. The end result is an extremely heat resistant seal
that is unaffected by line pressure or vibration.
