DELCO Trunion Mounted Eccentric Semi-Ball Valve

Eccentric half ball valve is a special ball valve with eccentric design and hemispherical spool. Eccentric design improves sealing performance has excellent sealing performance for leak-free operation, and the hemispherical spool reduces the contact area to minimise friction and wear; metal seals can be used in high temperature, high pressure and corrosive environments. It is also wear and corrosion resistant and can be used in harsh environments. Smooth operation and self-cleaning features reduce maintenance requirements. They are commonly used in the chemical, oil, gas, power and metallurgical industries and are ideal for fluid transfer and control.

    Trunion Mounted Eccentric Semi-Ball Valve

     1. The product adopts a hemispherical structure, horizontal installation mode, after opening the hemispherical body is located above the channel, completely separated from the channel, so the valve has a large circulation capacity, no impurity deposition.
     2. The hemispherical body adopts three eccentric structure, which is quickly separated from the valve seat when opening, effectively preventing the sealing surface from friction damage, reducing the actuating torque, and prolonging the service life of the valve.
     3. The high rigidity sealing surface of the hemispherical body and metal valve seat has a shearing effect, which can shear metal wires and all kinds of fiber fabrics without winding and deposition. It is the preferred valve for sewage treatment systems.

    Feature of Trunion Mounted Eccentric Semi-Ball Valve

    • Convenient switching: The ball valve opening and closing the ball surface and the valve body separation, no contact, small torque, flexible rotation, and start-up can eliminate the sealing surface peeling adhesion, to ensure a tight connection.
    • Smooth channel: Unidirectional sealing and eccentric structure make the valve open, the ball and the valve body loose, the flow channel is smooth, and will not produce blockage.
    • Good sealing performance: The eccentric structure of the sealing surface can automatically compensate for wear and tear, maintain sealing, and make the valve durable, safe, and reliable.
