Design Features FLOATING SEATRING Two independent floatingseat rings assure the bi-directional tightness of the valve from zero differential pressure to the maximum rated pressure. Anti blowout proof stem permn the replacement of the stem seals with the valve inthe full closed or open pos ilion. The ball is fixed and the seat rings are lloating, free to movealong thevalve axis. As the pressureincreases the ftuid pressure pushes the seat rings against theball.

DOUBLE BLOCK AND BLEED Independent spring loaded floating seats maintain contact with the baJI and provide an effective tight shut off at tow pressure differential. Independent upstream and down stream seats permtt raining of fluids from the body cavity, allowing double block and bleed operation. BODY JOINTS The dooble body seals O·rlngs and lire safe grapMe gasket in all static joints of the body components ensures protection against external leakage and fugttive emission requirements.
