Feature
Bubble-tight shut off at full pressure rating
Seat and disc are the only two valve parts in contact with the medium
Superior design for abrasive and erosive media
Very low pressure drop
Top bushing absorbs side thrust loads
Hub seal provided by preloaded contact between flatted seat surface and disc hub area for positive sealing at all disc positions
One-piece wafer thin disc stem gives the very minimum to obstruction to flow
Field replaceable seat isolates the body and stem from the flow
Molded-in O-rings provide flange sealing and eliminate need for gaskets
