      Features

    Due to integral type body without any pipe connection therefore not subject to the pipe or bolt stress and the pressureproof valve housing is not affected by the pressure jump. 
    The V-shaped body design, even in the case of low flow or high viscosity medium, can ensure accurate control in the entire measurement range.
    Leakproof and durable valve seat is installed a stainless steel inner cup-shaped PTFE  or Oring at its outer diameter, valve seat is made of large section WC-CO hard alloys ,   alloyed curved spring has further enhanced the structure of the seat.
    When the valve is closed, produced between V-notch and seat wedge shear, and both have a self-cleaning function and prevent the ball core stuck, especially for high viscosity, suspension, pulp and other unclean, fibrous media occasions.
    Because the V-notch ball shears the metal seat , so especially for fibrous, tiny solid particles and slurry medium.
     The worm-gearing V-notch ball valve also has the adjustable and reliable positioning ability ,approximate percentile flow characteristics and wide adjustable range.
    Using leaf spring loaded movable seat structure so the seat and ball will not be jammed or separated , reliable sealing and long service life.
