 ss304 segment  ball valve with pneumatic actuator 


Product Overview                                                              

   Pneumatic  control segment  ball valve is equipped with FOSQ series pneumatic actuator to adjust the pressure, flow, temperature, liquid level and other parameters.

    A segmented ball valve is similar to a conventional ball valve, but with a contoured V-notch segment in the ball. This control valve has good rangeability, control, and shutoff capability. The V-notch ball provides positive shearing action and produces an inherent equal percentage flow characteristic. It provides non-clogging, high capacity flow control. The V-notch ball has been specially contoured to maximize capacity and enhance seal life and shutoff integrity.  V-notch ball control valve bodies are suited to control erosive or viscous fluids, paper stock, or other slurries containing entrained solids or fibers. The paper industry, chemical plants, sewage treatment plants, the power industry, and petroleum refineries use such valve designs.
