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. |
