One Piece Ball Valve

One Piece Body Ball Valve

  • 01Mechanical stop

    • Ensures correct ball orientation and prevents misalignment in closed and open position.

  • 02Blowout-Proof stem

    • Ensures the valve stem cannot be blown out of the body in the event of the gland being removed while the valve is under pressure.

  • 03Matched ball and seat sets

    • Mate lapped ball and seat are self wiping to minimize solid build-up. All metal seats are wide faced design for reliable tightness and long life service.
    • Seating surfaces are protected from erosion in the fully-opened position.
    • Zero leakage sealing

  • 04Gland thruster

    • Is machined for a continuous tight connection with the stem and packing box to prevent packing extrusion and maintain stem alignment in operation.

  • 05Inconel 718 loading rings

    • Maintains tight contact between seats and ball, protecting seats in and open and closed position.
    • Accommodates high-temperature transients, allowing thermal expansion.
