  • Pneumatic soft seated ball valve Featue

    Pneumatic soft seated ball valve is a rotary type shut-off valve, and its structure adopts a bidirectional sealing design of a movable seat. The ball of  Pneumatic soft seated ball valve has a large shearing force and self-cleaning function when there is no gap between the two-way sealing seats, and is especially suitable for controlling fibers and suspensions , viscous media or abrasive fluids with fine particles in high temperature, high pressure Oil, Gas, Petroleum, Petrochemical, Chemical, Power Generation, Pulp, Paper and Mining industries.soft seated ball valve can be equipped with Pneumatic actuator, Gas over oil actuator, Electric actuator, Electro-hydraulic actuator to realize the functions of cutting, distributing and changing flow direction.
