DESIGN FEATURE
Fire-Safe certified, floating ball, blow out proof stem, flanged
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.
