Diaphragm valve pneumatic actuator PTFE PFA Lined

Diaphragm valve pneumatic actuator PTFE PFA Lined

Lus piav qhia luv luv:

Pneumatic PTFE PFA Lined diaphragm tswj valve yog tsim los ntawm pneumatic diaphragm actuator, ncaj nraim los ntawm ib lub rooj fluoride (PTFE, FEP, PFA) Lined qauv. PTFE, PEP, PRA, lub siab siab hauv ob sab phlu fluorine yas txheej txheem.Pneumatic PTFE PFA Lined diaphragm tswj valve muaj peev xwm tswj cov ndlwg ntawm acid, alkali, aqua wang thiab lwm yam corrosive media, tshuaj lom volatile gas thiab kua media.Yog li ntawd, Pneumatic PTFE PFA Lined diaphragm tswj valve yog dav siv hauv tshuaj, metallurgy, tshuaj thiab lwm yam lag luam.
