1. Zoo corrosion kuj: lub puab kab noj hniav ntawm Pneumatic fluorine lined tswj valve lub cev, core, lub rooj zaum yog lined nrog 3 hli tuab fluorine (PTFE, PEP, PRA), uas muaj peev xwm tiv taus corrosive kua.
2. Zoo sealing kev ua tau zoo: ob chav sealing nrog PTFE bellows thiab packing.
3. Cov dej xau tsawg tsawg, vim tias Pneumatic fluorine lined tswj valve tub ntxhais thiab lub rooj zaum yog cov foob mos, cov dej xau tau deb tshaj li lub teb chaws Ⅳ tus qauv.
4. Kev hloov kho siab: Pneumatic fluorine lined tswj valve txais qhov tseeb thiab me me pneumatic thiab hluav taws xob actuators, me me thiab lub teeb hauv qhov hnyav.
