Design Features

FLOATING SEAT RING Two independent floating seat rings assure the bi-directional tightness of the valve from zero differential pressure to the maximum rated pressure.

SELF RE·LEANING SEAT DESIGN When the body cavity pressure exceeds the down stream seat spring preloaded force, the differential force in the cavity area pushes the downstream seat away from the ball, the body cavity pressure will automatically relived. And then seat returns to the ball under spring loaded action.

STEM Anti blowout proof stem permn the replacement of the stem seals with the valve in the full closed or open pos ilion.

c__ TRUNNION-MOUNTED BALL The ball is fixed and the seat rings are lloating, free to move along the valve axis. As the pressure increases the ftuid pressure pushes the seat rings against the ball.

L_ ___ ANTI-STATIC DESIGN The electrtc conductarnce between all the metallic components.

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.

FIRE SAFE, PRIMARY SOFT SECONDARY METAL SEAT. A resilient material is inserted into the metal seat holder to provide a soft action in addition to the melal sealing between the ball and the seat rings. fn case of fire soft insert goes burnt and spring loaded seats insure metal to metal sealing.
