PTFE Swing Check Valve
Featuring fully-lined PTFE construction engineered for unidirectional flow control in critical systems. Its low-torque swing disc enables gravity-assisted sealing, delivering reliable backflow prevention against corrosive media and pressure surges while eliminating contamination risks in ultra-pure processes.
Key Features:
✔️ Zero Backflow Sealing：Self-aligning disc enables low-pressure drop flow + instant reverse sealing
✔️ Wear-Free Operation：PTFE-on-PTFE bearing surfaces prevent metallic contamination
✔️ Water Hammer Resistance：Cushioned seating mechanism absorbs line shocks
✔️ Ultra-Clean Compliance：All-nonmetallic design meets FDA 21 CFR standards
Critical Applications:
▸ Unidirectional media transfer in bioreactor feed lines
▸ High-purity chemical backflow prevention for semiconductor wet stations
▸ Electrolyte loop protection in Li-battery circulation systems
▸ Terminal distribution networks in UPW plants
