Quality Inspection for Globe Control Valve With Pneumatic Actuator And Smart Positioner - fluorine Lined pneumatic control valve – Hoyee Detail:

Pneumatic fluorine PTFE PFA lined control valve Features as below

1. Good corrosion resistance: the inner cavity of Pneumatic fluorine lined control valve body, core, seat are lined with 3mm thick fluorine (PTFE,PEP,PRA) , which can withstand strong corrosive fluid.
2. Good sealing performance: double sealing with PTFE bellows and packing.
3. The leakage quantity is little, because the Pneumatic fluorine lined control valve core and seat are soft seal, leakage was far below the national Ⅳ level standard.
4. High adjustment accuracy: Pneumatic fluorine lined control valve adopts precise and small pneumatic and electric actuators, small in size and light in weight.
