  • For use in on-off powder service such as polyethylene, polypropylene and hydrocarbon vapor mixture etc.
  • Superior seating: ANSI/FCI 70-2
  • Spring loaded seat maintains close contact with ball assuring tight sealing even at low pressure. This results in stable opening and closing torques at high differential pressures over a wide range of temperatures.
  • Scraper design for metal seat mechanically minimizes residual powder between surfaces of ball and seat to maintain seal ability during operation and to maintain smooth open-close action.
  • Powder proof devices around seat areas. The spring area is shielded from contaminants by means of innovative ring to provide a constant and stable seat loading to ensure smooth operation.
  • The valve stem is made of low alloy steel to maintain high strength. Electroless nickel plating for corrosion and abrasion resistance.
  • A non-lubricated dry PEEK bearing with low friction (for upper stem and lower stem) provides high abrasion resistance.
  • Allowable min temp. of the actuator is -45°C.
