Series Powder Discharge System
Brand: KTMA solution for powder handling applications, suitable for high speed and high frequency polyethylene (PE)/polypropylene (PP) processing applications.
Features- 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.
