I-diaphragm valve actumatic pneumatic PTFE PFA Ifakwe umugqa

I-diaphragm valve actumatic pneumatic PTFE PFA Ifakwe umugqa

Incazelo emfushane:

I-Pneumatic PTFE PFA Ivalvu yokulawula i-diaphragm enomugqa iqukethe i-pneumatic diaphragm actuator, ngqo ngesihlalo esisodwa se-fluoride (PTFE,FEP,PFA) Isakhiwo somugqa. I-PTFE,PEP,PRA, i-high pressure lining fluorine plastic process.I-Pneumatic PTFE PFA Ivalvu yokulawula i-diaphragm elayishiwe iyakwazi ukulawula ukugeleza kwe-asidi, i-alkali, i-aqua wang nezinye imidiya egqwala kakhulu, igesi enobuthi eguquguqukayo kanye nemithombo ye-liquid.Ngakho-ke, i-Pneumatic I-PTFE PFA Ivalvu yokulawula i-diaphragm enemigqa isetshenziswa kabanzi kumakhemikhali, insimbi, imithi nakwezinye izimboni.
