DESIGN FEATURE

Split body, full bore. Fire-Safe certified, trunnion ball with floating seats, 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 balancing hole avoids overpressure in the cavity with the valve in open position.
Asbestos free.
