Top entry trunnion Ball Valve Features:
1. Anti-static structure: Trunnion top entry ball is provided with the anti-static structure and adopts the static electricity discharge device to directly form a static channel between the ball and body or between the ball and body through the stem.
2. Double block and bleed(DBB): Both seats hold their respective pressures independent of the body cavity pressure which is ideal to verify the sealing of the seats.
