DESIGN FEATURE
One piece body, full bore. Fire-Safe certified, floating ball, blow out proof stem, wafer connections.
Non-removable antistatic devices assure electric continuity between ball and body through the stem.
All wetted component materials and bolting meet NACE MR.01.75 latest edition as standard.Cavity pressure relief hole avoids overpressure in the cavity with the valve in open position.
Asbestos free.
