Selection & Application FAQ
This plastic or PTFE non-metal contact rotary valve is used when the conveyed material requires anti-sticking, anti-corrosion or reduced metal contact during discharge.
When is PTFE or plastic material useful?
PTFE and plastic contact surfaces can help with corrosive, sticky or sensitive powders where metal contact should be reduced.
Is it suitable for plastic pellets?
Yes, the valve can be matched to plastic pellets, resin powders, regrind and similar bulk materials after checking particle size and flowability.
Can the internal contact surface be customized?
Yes. FUWEI can provide PTFE, non-metal contact designs or internal coating depending on the material and temperature.
