1. Consists of full plastic body, weir structure, flexible diaphragm and operating components for corrosive, viscous and particle-containing media.
2. Integrated full plastic injection molding without metal contact eliminates rust and ion pollution for high-cleanliness and strong corrosion conditions.
3. Weir-type sealing structure realizes friction-free jamming-free operation and tight zero leakage cut-off via diaphragm compression fitting.
4. Weir platform prevents medium retention and realizes automatic cavity flushing to avoid blockage by viscous and crystalline media.
5. Widely applied in pharmaceutical, fine chemical, electroplating, semiconductor and environmental protection industries for special corrosive fluid control.
1. Exclusive weir-type friction-free sealing structure resists bending fatigue for frequent switching and extended service life.
2. Stuffing box free and shaft seal free design eliminates stem leakage risk, suitable for toxic, volatile and high-cleanliness media.
3. Partition weir flow channel achieves complete cut-off without residue or crystallization for chemical liquid, slurry and particle fluid control.
4. Full anti corrosion material range matched with composite diaphragms delivers excellent temperature and corrosion resistance.
5. Multiple connection options including true union enable pipeline-free disassembly and low maintenance cost.
6. Smooth dead angle free inner cavity meets high-cleanliness standards such as pharmaceutical GMP and semiconductor ultra-pure water systems.
