Features
•
The compact wafer thin body
provides extreme low weight.
•
Minimum width of body
allows installation between
various flange standards.
•
Seating O-Ring placed in
groove on body and is
easily replaceable.
•
Low pressure shut-off, even at
very low differential pressure;
due to disc rotational axis
location; which fully closes the
valve.
